Have you explained to your mum what's going on and how you feel?
Why wont it feel okay to meet with your friends? That's what friends are for, support when you need it.
I know the feeling that you don't want a degree, it's just up to you how far you want to go in life, if you're happy settling for a lower branch on the tree that's okay.
Maybe more research would yield more results in order for you to get the information you need. Google is everyone's best friend

Have you been looking round for different colleges then? Grab a few prospectuses and browse through and see where you want to go. There's nothing stopping you from moving and starting again. At least you have the strength to carry on moving forward.
Best of luck!
