I'm so sorry you feel this way. But you definitely have support here. We understand the journey that is bipolar and can empathizer with you.
At my T appointment yesterday I was telling him that when I'm upset and I go into my crying spells, I tend to focused on how much I am alone and that nobody likes me. He told me compliments on my personality and can't understand why I would think that, and others have as well, but when I'm in a depressive fog, I really can't see it and I think I'm a horrible person. It's hard to see when jaded by depression, but it's true what others say, otherwise they wouldn't say it.
