Basically what the title says. Often, I find that when I express a concern or fear to someone, I feel embarrassed about doing that. I feel like I'm a terrible person for putting that on someone or like whoever I expressed it to doesn't care (even though they are close enough to care and probably do). I also feel embarrassed about just existing sometimes...I'll feel disgusting around certain people who are close to me because I think they hate me for liking them as people or being around them or talking to them about my life and my BPD. I feel guilty for taking up their time and needing there support because of my BPD (and OCD). 

These types of feelings linger for a while, usually 18 hours to a couple days. I feel uncomfortable, but it seems like I never know why consciously until I think "oh yeah, it's because I texted X to Y person" or "it's because I'm afraid FP hates me because of Z thing". It's like my subconscious knows why I'm bothered and is still living in that past moment and bringing that uncomfortable feeling forward, while my conscious mind just feels uncomfortable and wants to hide (and can't focus on other stuff), but doesn't really know why. Doesn't anyone else experience this? Should I bring this up to my therapist?
