How do I get over him?

Ive been depressed for the past month or so and on top of that, had been feeling my partner distant. When I’m with him I forget everything. I finally ask what’s wrong and long story short, we break up. I’m feeling so sad and emotional, I’m pmsing too jajaja. I don’t have any friends and don’t know what to do. He said he’ll think about us and give me an answer if he truly feels something about me, I don’t think he does... Everyone enters my life, breaks my barriers, makes me happy and when I feel that I’m at a great place they leave and I’m so tired. Not even talking romantic real, but friends too. I’m so damn depressed and longing a change, longing some good friends, longing happiness...
