I agree you should go to rehab about the drug use or possibly a dual diagnosis type hospital that can work with both issues. They will help you get off drugs first and be there to help with what happens after that. Since you use to do so well in many areas and especially language you may have aspergers' syndrome. Social skills not be second nature of you like it is for others but they can be learned! There is much, much hope for you but you must get off street drugs. That will be your new beginning...even though you have had a tough time in your family home. Good Luck!!
