You said that you feel detached. That's part of dealing with a lot of trauma it's called disassociation. Yes, it's normal. Disassociation is also part of the borderline diagnosis (waving hand). I'm not saying you are a borderline but I am and I struggle with disassociating when I deal with past trauma.

You said you missed him but don't feel close to him. What did you miss? I'm just curious I'm not trying to be snarky.

I take little things personally all the time. Someone said being borderline is like having the emotional sensitivity of skin that has third degree burns. I feel like I'm constantly fighting not to take everything as a personal insult or hurt. I fight back tears all the time.

Good luck!
