I am sorry you are going through this, I can relate to some of your challenges, even the laugh part. I don't think it's bad to laugh because at least that helps "some" in getting the words out that go with the emotional challenge that trauma presents. I went through a period of about two years myself where I would wake up from a night terror, which is basically having flashbacks while sleep, and being disoriented, yes, probably for the amount of time you describe, or at least it felt like it.

What you are having such a hard time with is another invading and totally disrespecting your boundaries and that took something significant from you. That is very hard to put into words. The brain/mind is worried about having too much emotion present, so that is why you disassociate. I think that is incredibly hard to tell another individual too, because there is a fear that other individual will make judgements or not respond well, which would only add to the injury.

The average person has no idea how much work it can be to find ones way to healing and making gains on this challenge.

I take it one day at a time, some days are hard and I work on being patient and caring with self.
