Struggling with PTSD and Sleep: Need Advice

This is kinda hard to talk about, but I’ll be honest, I’ve actually never opened up to a therapist fully about the effect being sexually assaulted had on me…Mostly because it’s just so painful to remember, but the thing is…it’s starting to have physical effects on me that I can’t ignore. Ever since it happened about two years ago, my sleeping patterns and night terrors seemingly are only getting worse, and more erratic. It took me a while to be able to sleep with my boyfriend again, and on countless occasions he’d hear me screaming in my sleep, sometimes waking up drenched in sweat, and have to comfort me back to sleep. But lately, for the past few months, he’s been saying that he’s been seeing me claw at my face with my nails in my sleep …Now, I have no knowledge of this, and never remember it, but one day I woke up and i’d scratched a giant gash into the side of my neck in my sleep without knowing. When I was assaulted, I’d had a scarf wrapped around my head and neck, so I can only infer this is something to do with my PTSD from that…but since my Quetiapine keeps me pretty sedated at night, there’s pretty much nothing I can do to stop myself when it happens. I never remember the occasions my boyfriend tries to wake me up to stop me scratching at my face, and ever since I’ve become knowledgable about it, it’s just gotten worse, and I have new scrapes or scratches on my face and neck almost every couple of days now, without me even knowing it. This has been happening for a few weeks now, and I just want to know if anyone else has experienced anything like this…? it’s gotten to the point I’m ashamed and humiliated to even go outside sometimes because my face is starting to get so scarred looking…one person at work even jokingly said I looked like a drug user, and even though I just laughed, it’s like what the hell do I even say to explain that? I can only be thankful that masks are still optional (I’m a server at a restaurant), but I still feel like I stick out because it obviously doesn’t cover everything, and most of my coworkers don’t wear their masks anymore as the mandate here is lifted I’ve just been feeling so alone and out of control lately, and don’t have a therapist currently to be able to get some of this stuff out. (I’m working on getting one soon) - Apologies for the long ramble, I’ve not talked about my PTSD much before so this is all a bit new in ways Hope you’re all doing well and having a wonderful day ;)
