So this week I flew out of the Midwest and had a small vacation in New England with my best friend, sister and her roommate. During the entirety of this trip. My body shut down. And at first I thought it was because I was just really tired, but each day I would gain more sleep, and my body would still feel just out of touch, everything felt like it was just unreal and I just experienced this throughout the entirety of the trip. It wouldn't let me enjoy anything and I did enjoy myself for the most part, but I just didn't feel like myself or like I was there. I got home yesterday and I am still feeling this way, should I go to a doctor, ER or what should I do..? The last time I did this was the last two days at my old culty Christian camp where I was abused, outed and just treated like shit. I feel safe around the people I was with, this week, but I just wanna understand why my body shut down... I have CPTSD due to being in a cult my whole life, being abused by them, being mentally and emotionally abused by both of my parents' sides of families, being molested by my cousin and being molested, physically abused, and harassed by a very close male friend (I'm a gay male)

What is causing this...? Can this happen to people with PTSD/CPTSD?
