Im confused or lost not sure what it is.

For a couple of weeks constantly plagued and non stop mood swings. Like i had a minor memory that plagued and made me think myself the most negative possible and felt like i deserve to be miserable. But then over the weeks i had crazy racing thoughts and more bad feelings of myself and fantasies nonstop after watching a few shows and there are scenes that replicate in my head. I also get violent or crazy random dreams and nonstop guilt for minor things or fears from my ocd which i did have pocd at one point. When i have mood swings it logically convinces my thoughts its just anxiety and im normal but when miserable says there is a lot wrong with me and im bad person and that is the truth my mindset most of the time.
