as a side note i feel increasingly detached from reality and my sense of self
Who's reality and self do you find yourself attaching to?
i'm not quite sure. no one in particular just not my own, sounds a bit weird but i feel like im not really at the wheel
i've felt the same since i broke up with ex, i don't know why im doing any of this, i think its dissicociation
Sounds more like running away from your feelings from the sounds of your OPs lately. The only reason you can't see yourself is over how much you don't recognize your behaviors when compared to the construct self you believe yourself to be, the contradictions are screwing with you.
Stop running and you'll figure out why you're doing this, keep running and it'll self-perpetuate. You aren't out of control, you're just spending all that energy on damage control versus your own perceptions of yourself.
Learn that how you're behaving now is just as you as you are when you're doing otherwise and from there the introspection can kick in.
