Does this sound like Dissociative disorder?

I am 23 years old and have struggled with depression, anxiety and anger disorders due to past trauma. I'm starting to think there is something else wrong with me... Here are my symptoms. Please comment if you know anything at all about dissociating...

Memory problems. SEVERE. To the point im starting to think I have begun to lose my education and everything I have been taught. Problems coming up with words I know, don't remember movies I have seen, things I have done or said. I feel mentally "slow," sort of dazed and confused.

I don't feel like I'm really "here" like I could sit in a corner all day and watch the world go by

I don't have an identity. I don't have things that I really enjoy doing, because I prefer to sit in my own little world and have trouble really breaking out of this so called "shell" or bubble I'm in. I feel like I'm in a bubble, and everything is slow motion.

Nothing is really enjoyable to me. People, things, places, I'm just NUMB. What's wrong with me? Am I dissociated? Because it feels like it's getting worse.
