Wow, I feel like I could have written this word for word.
For me, those feelings of disconnect and not enough and too much relate to my BPD traits. It's like everything is too much and nothing is enough. I have some trouble remembering things too - and I attribute it to the fact that I don't have continuity between episodes; whether it's friends, therapy, work. Every interaction stands alone, not part of a thread. I've gotten better at the continuity part, but it still has its challenges.
