I have some random shit like OCD and seasonal depression. I need someone to try and maybe give me a idea of what could it be so I could look further to read about it. I don't a real diagnosis I just want to research this thing. So lets get into it: when I have a really deep thought , really deep like a really bad feeling of a future thing , or thinking about the universe and how everything is unexplainable or traumatic events I have a tick , the tick includes shaking my head up and down a few quick times and an almost unnoticed some would call orgasmic feeling in my neck. I had it since I remember myself and would fucking like to have an idea of what it is. Don't delete the post I don't really want people to diagnose it , just give me an idea of what could it be.
