Hi, NNRO9, and welcome to Psych Central! I am sorry you can't afford meds. I don't know how I would function without them. The only thing off hand that comes to my mind is going to the emergency room. I think they have to see you even without insurance. I suggest you check into that, anyway.
Is there any way you can get some insurance--maybe a national health program?
Meanwhile, try to take deep, long breaths; listen to relaxing music; just try to relax the best you can......
Do your friends know why you are acting the way you are? If so, then I would think they would cut you some slack and be understanding.
