Break up

My boyfriend and I broke up after a month of dating. I know that’s not a long time, but we talked/flirted for a year and a half. I am heartbroken. He was my second relationship and it really meant a lot to me. I opened up to him about self harm and anxiety. He said we could stay friends if I wanted to and I do because I really care for him.

I guess I’m asking y’all for advice on how to cope. I have bad coping skills as I mentioned above. I want to stop crying. I want to stop constantly checking my phone for a notification. Please help me.
