Medication

During the past few months I have had trouble sleeping and I haven't been eating very much. I get extremely mad, extremely easy and tend to severly cuss people out for no apparent reason. I tend to feel worthless a lot of the time and I can't concentrate. I have thought about turning to suicide. Sometimes I will be sitting in class and my mind wonders. I forget things easily as well. I have now turned to marijauna, which gives me a feeling of self-hope. Is there something wrong with me? Do I need to seek professional help/medication?

All kinds of narcotics will only make things worse in the long run. See a psychiatrist or psychotherapist, they might be able to help you.
