Depersonalization/derealization disorder

Does anyone else struggle with this? If so, how do you cope? It’s gotten a million times worse since finding out I’m pregnant. I’m almost 13 weeks and I’m extremely miserable and constantly isolating myself because of it. I feel like I’m not myself and sometimes when I look at myself in the mirror I don’t recognize who it is and I start to panic and sometimes I start screaming. I feel like I’m living life through a dream. I can’t stand living like this anymore. Sometimes it feels like I’m underwater I can’t even explain it. But when it happens I want to get away from everything and everyone but I can’t and I start to panic
