Broke up after 3 years.

Idk what to do. What to think. Me n my bf broke up yesterday and I feel so numb. I want to cry but I can't. I'm sorta glad we ended but at the same time I miss him. He was manipulative and controlling. I have therapy classes (for anxiety and depression) tomorrow so hopefully that takes my mind off this but idk what to do. I don't really have many friends to go out with so I'm almost always stuck inside. Any ideas? Tbh I really wish I had some ice cream rn lol.

I know he's pretty upset too, but I didn't want to go back into an unhealthy relationship.
