Jealousy, Lack of Happiness and Support - not sure what else to do(long post)

Good morning everyone. I wanted to share some feelings I've been carrying for years, and I am hoping to pinpoint what my issue is in addition to my Adjustment Disorder. Here it goes...

I am having a major problem with jealousy and learning how to be happy despite all of the terrible things that have happened to me. I have an annoying habit of comparing my situation to others; it's gotten so bad that I had to deactivate my Facebook. I feel like I have no friends, no support, and that no one really cares what I've gone through and what I am currently dealing with.

1) I am still stewing over a roommate situation that went awry last year. Back in July 2012, the boyfriend and I moved in with a mutual friend. We'd only been there a month before the girl who eventually became the girlfriend showed up, and it went downhill from there. My ex-roommate essentially let her take over the house, and then he had the nerve to tell us to get out because their relationship was getting serious and they needed the space. I confronted him about it, and never got an answer. I am still pissed that their relationship blossomed while mine suffered, and being forced to find an apartment when I was not financially ready to do so. I now live in an apartment I hate because I had to move suddenly. Every time I walk in the door, I get angry about my situation. Not to mention, my ex-roommate share mutual friends, so that in and of itself is awkward. And I am sure the mutual friend has heard both sides of the story, and I have no doubt they conflict. When I see pictures of my ex-roommate and his girlfriend being happy and living the life, it REALLY angers me because I know what they did to me in order to gain that.

2) I finally confronted my mother about all of the abuse and neglect that she's put me through since I was a child. Not surprisingly, she pulled the "blame the victim" card, and took no responsibility for what she's done. She blames me for her getting arrested back in the 90s for child abuse/neglect. She hit me multiple times with a belt and a YMCA counselor witnessed it. I don't remember much about the court case as I wasn't really present, but I do remember them taking pictures. In the end, they found no real hardcore evidence of abuse/neglect, and she got probation only. However, she is of the mindset that I, an 11-year old at the time, was responsible for her, an ADULT, reactions. Ok sure, I had some issues as a kid and sure, I did things I shouldn't have as a kid...but it hurt that I didn't get an apology, and that she blamed me for everything. She said I needed to stop having a chip on my shoulder because it's the past and that I need to get over it. Ok...

3) I had a "friend" borrow 400 dollars from me back in 2009. She has not attempted to pay back an single cent. This was the situation that made me realize that I had no true friends. A lot of people knew she owed me the money, because continued to party and be friends with her after the fact. I am not friends with a majority of those folks anymore. At that moment, I told myself that I would never put myself on the line for anyone ever again.

It is events like these that spark my jealousy and make me question if karma really does exist. I am so angry and hurt at the fact that the same people that have done terrible things to me are happy and living the life, while I am over here struggling with changes that could have been avoided(personally and financially). I don't like seeing my ex-roommate and his girlfriend happy, because I don't think they deserve it. I don't like seeing ANYONE who has screwed me over or harmed me being happy in any way. I feel like the karma that should have been imposed on them, is happening to me. I live in an apartment I hate, my relationship is on the rocks, and up until this past Monday, I was going to be unemployed(thanks US government).

In conclusion, I have completely abandoned Facebook. I have not talked to my parents or any other family members, as I feel they are not supportive. As for social media, I stick to Pinterest and Instagram, as I have more control of what I see. I look at funny pictures, try to find recipes for food, and only communicate with acquaintances that try to offer positive advice or are just positive in general. But it's only a very temporary fix. I am still very unhappy and angry...and no one has offered up an apology. It just always seems to be my fault.

if i were you i wouldn't wait for an apology, since if you have't gotten one by now you probably won't. you have to get on with your life and realize these people are probably happy together, you just got stuck in the middle. i wouldn't be jealous of them they should be jealous of you and that would happen after they see you get on with your life, there are a lot of fish in the sea and you shouldn't worry about it anymore, the person who broke up with you may even regret it after awhile, but if they do you you deserve better now anyway and have it in your reach to get what you want. you can find love again and you do deserve someone better.
