29f and have PTSD from an abusive relationship from when I was 19-24. Been on Sertraline (various dosages) for 3yrs and have overall seen a big improvement in emotional swings, anger, and sense of guilt/dread. 

But I still find myself accidentally doing all-nighters just because I can’t stop thinking about all possible outcomes of a situation. I’ve always done this since being a child, every so often I’ll just have a night where I won’t sleep (common if I have something significant coming up) because my brain can’t switch off from thinking about all possible scenarios and what I would do/ how I’d react in that situation. 

Does anyone else have this as a weird coping mechanism for ambiguous situations? And how do you manage it? I’m getting to a point where it’s now starting to really affect my life as I’m either always tired or I miss things due to oversleeping when I do finally rest. 

I never spoke about it to my parents as a child as I just thought it was normal, plus I was young enough for it to not really affect my day to day. 

I’d probably say it happens at least every 3/4 weeks
