feeling down 😔😥

I just graduated high school and I noticed I didn't have actual friends to take pictures with. Just a couple of people here and there. I started to go out with my boyfriend in 11th grade and since then I guess I pushed my girlfriends away since I'd always be with him. After the honeymoon phase was over I wanted to hang out with my girlfriends but I realized we'd grown so apart. Today I've felt like shit about it and regret it. Even though my boyfriend and I are going to the same college I don't know if we'll stay together. I just feel like I wasted my time in high school and feel guilty.😥I don't know what to do.
