I'm so lost

I'm 20 years old and I'm currently in my second year at a community college. I'm a quiet person and I've struggled to find/make friends and it's so discouraging seeing people walk around with friends. Most of my friends from high school are now out of state or we just grew apart. I don't know what I want to do with my life, things haven't been good lately and I'm not in a good head space. I'm hoping to drop out of school this up coming fall semester and just work full time. But I really don't know what to do and I'm so lost I just feel like a depressed piece of shit and that I don't belong any where
