i understand i too have been in the situation you have been i also did online school halfway through high school. i had and still do but back than horrible anxiety crippling anxiety. i don't treat or am a doctor but wellbutrin gave me the motivation to get up and going and a good antianxiety med leveled me out so i could go and get a job...(how am i supposed to get a job and be around people if i couldn't even go to school) that's what i tried telling my mom when i was younger. ssri's did the polar opposite and actually made me even more depressed and suicidal. except for paxil but it doesn't work anymore for me but when i was 15 i was on 60mg and it worked for anxiety but it worked where you could litterealy come up and stab me and i would look at the wound and just move on. but i couldn't be around people without being on heavy medication.
I just want to tell you there is hope...i am a very social person now...i don't take meds for my anxiety (every once in awhile i get a panic attack)i have ativan for that but i still have some anxiety but it is nothing like it used to. i am still learning how to speak right though/using my words right, all those years of antisocial behaviors. i was a straight F STudent had a .6 gpa and failed even the simplist of classes.

there are so many of us out there that have been in your shoes!
meds are a temp fix anf i hope you find someone to talk to professionaly but we are all here until you do.
