I started college this semester and in the beginning of the semester I used to interact with girls a lot because I was pretty much chasing them. I realized I was being needy and seeing attractive girls as a source of happiness. So then I stopped chasing them and started focusing on my own self. But now the problem is that whenever I see some guy with a girl on campus (even if they are just friends) I start feeling depressed. It's like a cycle. If I chase girls, it's depressing. When I stop chasing and focus on myself, I will see guys all around campus hanging out with girls and then I feel depressed. It's hard to have the right mindset to not feel depressed over this. Any thoughts and advice?
