Yes I had exactly that a long time ago. Anxiety, energy drain. Specifically for a few years I had incredible energy drain if around people. That started up when I was 18. I could not go to school or to a workplace. I stayed in isolation for 10+ years overall. (I did remote work.) I no longer have that sort of energy drain somehow, it went away after enough rest I suppose. The desire for isolation did not go away on its own though, it only changed 4 years ago when I ran into some guy who I tried to have a relationship with. That relationship lasted for a month but I never fell in love or anything, just the initial contact made me feel like I was connected.. for a short time or something. I never had that experience before I think? Not even before I was 18 and my normal default self. Then I just changed into this crazy and moody person afterwards lol and no longer wanting isolation. I'm 32 now btw if I didn't mention that.

Idk if that makes sense But this is why I wondered about some link if one is known between the two disorders.
