I have no one

I’ve been having to go through a lot for the past couple months. My ex promised me the world then ran off and gave it to some other girl he had been dating the whole time. I’ve been struggling with being bullied, I’m in college I thought that stuff ended in high school 😔. I also struggle with depression. I tried opening up to my one friend that knows about all of this but he didn’t say anything at all. I feel like people are constantly throwing rocks at me waiting for me to fall and it sucks 😞. I just want the pain to stop.
