Hi Myoasis ~ I know how you must feel. And I know the loneliness of social anxiety disorder too.
Dearheart, is there some way you can get into therapy? Do you have insurance where this would cover it? Even if you have Medicaid, that COULD cover it. Check with your case worker if you have it.
You really should see a therapist if you can. Therapy can help you work thru these issues and help you conquer this disorder.

There could be some other issues too that are standing in your way that need attention.
If you cannot get into therapy, and are still in school, talk with your school counselor. He/she can help you. That's what they are there for. Don't be afraid to talk with them, as it's confidential. They won't tell your parents as long as you're not intending on harming yourself.
Please let us know what happens, okay? We DO care about you. God bless and please take care. Hugs, Lee
