How to cope with breakup?

Ok then you most likely do not have BPD - intense emotions can be a symptom to a variety of things, I am not a psychiatrist or psychologist so I wouldn't want to try to diagnose you - but the biggest question is: does any of the things you describe about yourself seem to cause you difficulty in your day to day life or in most all of your relationships?

"Feeling of emptiness" - I don't feel empty. I usually feel something, I can hardly say it's emptiness.
I never found myself being paranoid, I am more or less naive when it comes to the intentions of others I think.
I am too perfectionist to idealize people too, I see many faults in many people, it makes it hard to open up and to be warm in a relationship. This is the reason why the other thing about intense relationships can't be true too... I also don't want to make myself look a fool in a romantic relationship so I hold back as much as I can even after a longer time. And... The thing about the unstable ego image... just no... I haven't changed my opinion of myself in many many years and I've been following the same goals since elementary school really...so ... no

I do have intense emotions... which might seems borderline...but as far as I know, I do not show much of other symptoms... I am just hypersenstive, but also in very introverted and reserved manner...I don't show much of what I feel out of the fear of being seen as stupid or too emotional, so I usually play it really cold and cool.

Also...I am very judgmental of people myself and it's hard to please me. I tend to put people down with just one look and I am quick to make judgements about people. So there are really just a few people I feel like they are good enough, but then I do not feel like I am good enough myself. It's like a split where I also feel better than most, but also far worse then them if it makes any sense... I also have very specific criteria for people and I limit myself to only meet those who are a part of some of my ideal... And I notice how far or close I am to that ideal myself... Scan for people's imperfections and perfections to see who's better and who's worse...It's basically a struggle between being really ashamed and envious, but then at the same time being proud and selective, because I feel like I am very different than most and only those who understand and view the life the way I do are worthy of my attention.
My thinking is very abstract and idealistic and probably hard to stimulate by most of the common things.

Idk...if I make sense

Yes you make sense - may I ask if you have ever had a psychiatrist test you or been diagnosed for anything? You may want to read up on Avoidant Personality Disorder - I am not a doctor n not trying to diagnose you at all. To me it seems like those symptoms you described would become crippling to one's social life. Do you feel it has become crippling to your social life?

You sound VERY much like me. But I can get paranoid in my long-term relationship. If I was to start a new relationship six months ago I'd probably push the other person away.

I'm very reserved, I'm an introvert. I don't open up to other people, even though I can be nice and friendly to the them. The idea of opening up gives me exactly that feel of being violated. I also have lots of trouble with showing affection and my boyfriend is probably the only person who I can hug, kiss and say loving things to, even though he still says he's always more affectionate than I am. On the other hand I'm hypersensitive and I don't know why or how, but I feel things 10x stronger than others. I used to think everyone felt like that, but nope. It's something I struggle against, as I find it hard to put to good use and contrasts a lot with my poor interpersonal skills.

I'm also very judgemental. I'm not nasty, but I do scan people like you said even if my own self-image isn't the most positive thing ever and always thinking I'm not good enough and others have no reason to like me. I can't say I like most people I know too. This causes me great anxiety as I hate the idea of creating standards to categorize people but doing it myself. Very tricky.

May I ask you what are your hobbies or leisure activities? What do you do to get rid of stress? Are you involved with artistic production?

( some BP persons are originally wrongly diagnosed as BPD)

Getting over a relationship. Tough, isn't it. I think many forget that we grieve not just the hole but the change in life circumstances - especially if you relied on this person for activities and getting out. I realized I relied on my ex BF for most of what went on in my life. And I'm not just taking about things like going out. We went grocery shopping and ran errands together too. I made dinner for us often. I realise my anxiety was greatly reduced on account of someone regularly being present. It occured to me after the breakup that I really depended on him.

Thus it wasn't just the grief and hurt over the loss of a love, loss of an individual; but, it was also grief over the loss of how I lead my life.

Are you prepared to be friends, would having some sort of contact be okay with you?

A month after a very nasty breakup I have found myself on talking terms with my ex. Just that has greatly reduced the depression and anxiety - I don't know why, I don't know why it was a relief to hear from him. But, I finally feel a sense I can move forward - AND - live life (on my terms) again.

I think part of healing from the grief of a breakup is just that - feeling a sense that you have regained control over your life.

Borderline Personality Disorder is one that is often misdiagnosed - it took 3yrs of actual treatment before they even started with that diagnosis with me and then for 2years they yoyo'd back and forth between borderline and bipolar. I kept being told it was not possible I felt a certain way because the DSM said I should not so I finally got severely frustrated one day and told my psychiatrist off and told him I didn't care what the DSM said I am telling him how I feel n if the DSM says different than he has a wrong diagnosis for me and needs to do another complete psychological evaluation on me, so he rescheduled me gor an appointment that took an hour - and came up with my correct diagnosis, but borderline can hide itself as many things just as when you have a combination of things it may first appear as borderline - have you spoke to your psychiatrist about your concerns?
