Judging from your first post, this is not a goodbye thread, so I'll respond. I understand your situation, because I'm bipolar II just like. I know the undescribable pain you're going through and what a strong death wish it engenders. It's one of the reasons I'm here. I assume that you're struggling with social problems too, because so do most of us. We have smaller social networks, are more often singles, and so on. Yet, I know people with bipolar disorder II more severe than mine who have managed to build good lives for themselves. You're not doomed.
Are you in a depressive episode right now? If so, I think you should wait with this important decision, arguably the most important one in your life, until you're in your right mind again.
