Hi there, welcome to PC!

School is stresssful, so I definitely understand where you are coming from. I don't have any great advice when it comes to making friends, but I just wanted to add in my two cents about school. When I went back, I started off with a couple of classes before adding more so I could get adjusted to what it's like being back in that environment. And as Gemma advised, seek out counseling as needed. I didn't when I was younger and my whole college experience could have been different if I would have gone the first time. As long as you maintain a good sleep schedule, eat right and exercise, you should be ok. And see if there are any clubs available. I know community colleges may not have as many, but there are a few from what I remember when I went.

Good luck and I hope it all works out!!
