Hi and welcome. In terms of what to do, you'll definitely want to consult an professional who deals with psychological issues. Although some go through a GP, it's not a great idea, because psychiatric things are very complex and specialized -- beyond the ability of a GP, no matter how well-intentioned. (And like tnlibrarian, I learned that one the hard way.) They can be very useful though. In giving a referral.

No need really to worry about treatment types till you know what is going on. What it is that you might be dealing with, you know? Similarly, the types have various diagnostic parameters and often people do not fit neatly inside one. Sometimes it is neatly "enough" that that label is given to it, and sometimes it goes into a category called "NOS" (not otherwise specified). Then, there are situations where bipolar criteria are not met, but there is some similarity of symptoms noticed that led the person consult with a professional in the first place. Might be cyclothymia. Might be BPD, which is the acronym for borderline (not bipolar -- whose acronym is simply BP, but the letters cause a lot of confusion -- for obvious reasons(!)). I throw the BPD possibility out there not only because it is often confused with BP by the layman (and to further confuse matters, some people have both), but in your saying that you wanted to get a grip on your emotions because they are ruining your life ( on that btw). Emotions is the word that caught my eye. Interestingly enough, there is talk of changing the name of borderline to ERD -- Emotional Regulation Disorder, which would be a much much better name and actually reflective of the symptoms, which the current name is not. But I digress... (all the time... )

What was the question again? Oh. Right. So as you can see from above (and there's far far far more where that came from, lol), it's complicated. Hence the need for a psychiatric professional to sort out what is going on in one's individual situation, and it's best not to get too far ahead of oneself.

"How do you handle it?" Sometimes better, sometimes worse.
