I am 22 I started smoking drinking when I was 16 due to peer pressure. I started marijuana at 19 and codeine syrup at 20. But now since last 3 months I am clean no drug use. But my parents still dont trust me because I still look sick like drug abuser. They dont trust me. I have done thefts in my home. Because I couldnt continue my studies due to drug abuse my carreir is wasted and I can't study anymore even if I try to. I am unqualified so no on will give me job. I have symptoms of neuro disease like burning sensation in fingers of left hand soft erections confusion. When I tell this to my parents they say they dont have money to show me to doctor and get tests done although they have. Now I dont have friends or girlfriend because I have no money they all have started behaving with me as though they are superior and try to maintain distance or make fun of me. I am really depressed I can't understand what to do. I sometimes think sucide is best way to end all problems and make my parents realize money isn't everything.
