<human>: Can you provide a brief overview of the text?

I was dumped by my ex a month ago, and we had been in a relationship for 11 months. I was in love with him. He broke up with me because most of his memories of me are of me being angry at him. I have anger issues that I'm now trying to work out. 

I'm having a lot of trouble getting over him and I just feel like shit. Most days I wake up feeling alright, but when my mind starts thinking about him, I am consumed by sadness. 

I just had sex with another person and I feel horrible. It was meaningless, and that's how it felt. I used to be so okay with having meaningless sex before, so why is it so hard now?
