I would suggest trying to take control of you life
Explanation:
I did this and trust me it takes time.. you can't just make those feelings go poof and they go away but you can take control of your life slowly. What I did was clean a counter, or a small space to get me motivated. I then cleaned my room and made my bed listening to my favorite music ( try the ones I suggested you before ) and just danced around in my room not listening to anyone. Then I started journaling. Journaling really helps! It's like a diary but more therapeutic. You write down how you feel, a schedule, to-do list. Whatever you want and all you need is a journal and pencil. This is what I did and although I still have moments with negativity, it's going away slowly. Sorry if this is long but just try to focus on yourself before anything else. Don't listen to anyone else and if someone breaks you down just remind yourself. They aren't you and you aren't them.
