There goes my life out the window! Please help! NOT ONLY POINTS BUT HELPING A LIFE OUT!?

I have been in telecomunications for 9 months.. I have been scared to ask for help about my servier AD-HD. because in regular school everybody use to call me slowmo and it ended up with me getin kicked out cause of fighting. and i didnt want the same thing to happen in college. and now im about to get kicked out and lose pell. And i told my school administration about it and they are willing to help cause of my disability. but im might be geting kicked out before i can finally get help. im scared because i didnt tell them about my disability and failed almost all my classes since ive been in school. What can i do? Was i wrong for being scared? Is it my fault for being AD-HD? Am i just a dumb A**? what is there worth living for since i might be losing my dream career and i only want to do telecom. its my dream. Please help me! Is there any chance of me keeping pell with a .50 GPA? i had a 3.8 GPA but lost it cause i was scared of telling them about my AD-HD.. So will i lose pell? PLEASE HELP ME!
