Depressed over self

I’m going through depression how I’ve been treated, mis-used, and abused ~ over the last few years by the 1 person I thought I had a friend within with.

I ended my first toxic relationship recently. He started dating right away, and being mean to me about how much money, meals and gifts he gives to her with his paychecks. 

I had to break-up with him, due to zero % love (in the end) and he never stuck up for me. He was mean to me about my weight, but she’s bigger than me.

I’ve came to final closure that he had an affair on me, and didn’t want to try to fix things, and thought it’ll be cool just to dump me on spot to start all over again with another girl. I’m special needs too, and that hurt worse. He knew I would’ve still stayed with him, but he’s a bully. 

I’m figuring self discovery and self love/self care after my tragedy. Anyone else wants to join me? Boys allowed too.
