Given your age and position, your best strategy appears to be to contact a plaintiff-side employment lawyer in your state, discuss your case in detail, and devise a strategy to defend yourself. You may well be correct that your boss is scheming against you - but that alone can be both hard to prove and may not even be illegal (unless done for improper reasons - again hard to prove). By strategizing with a lawyer, learning what your rights are, and learning how to document events in the workplace, you will be in a strengthened position in the event that he attempts anything beyond his present level of bullying - and you will have a lawyer on your team in the event of any unwarranted disciplinary action or incident of discrimination.
