First off, PinkSoil is 100% right. Your symptoms, thoughts, and behaviors aren't influenced by whatever label you give them. A label is nice because it could clarify some of your psychology, but it's not crucial, and can even be misleading when you're trying to fit your issues into a certain defined disorder. Much better to drop all the labels, see what's bothering you, find the core, and then attack (or rather accept) the core. With that said...

I'm clingy and very love-y love-y but also intensely worried that it won't work or the person doesn't actually love me. If I'm rejected, I'm basically devastated, (I actually tried to kill myself after a rejection. I'm not sure if it was because of it itself or my interpretation.) feel like a failure and don't like that person very much anymore for awhile. I also divulge a lot of personal stuff in the beginning. There was one time where I admitted to a girl I was madly in love with her and she wanted to be friends only. I was obsessed about it and developed a very intense relationship that caused her much grief I believe and caused me pain that she wouldn't be with me. My love life is a mess...

You sound a lot like me. I get into relationships and I'm all about the person and I get very close. That's idealization, and it's a tool you use to feel closer than close, like the person would never even THINK to break up with you, which is a pain that's too hard to handle right now.

Whether we call this full-blown borderline, or mild-borderline, or depression, or Coca-Cola doesn't really matter, does it? You'll still have the same fears with the same behaviors that are causing the same discomfort. You still have this anxiety that people will leave you and you still need to find some better coping mechanisms to deal with the pain without freaking the %#@&#! out.

If I were you, I'd go to the bookstore and read up on borderline and abandonment anxiety. Find ways to work with your anxiety and befriend it instead of casting it away like an unwanted guest. Do your best to have patience in all of this. It takes time and steady progress to overcome these things but it can be done. In relationships, we play whatever games to try to avoid the depression that ensues after rejection. If you can see that your desperation to overcome your depression and anxiety RIGHT NOW grows out of the same need to avoid/overcome, then maybe you can give yourself a break for a little bit. Instead of investigate to dominate your fears, investigate for insight.
