What maybe people are waiting for is someone to answer you where it could help.I also started having problems after attending college.I also smoked the marijuana some when i was young,getting away from the crowd that uses such was best thing.Marijuana is a social event,try to see that it is not good stuff.it might help.Effects of drugs are usually not very good.I started hearing things right after I got my wisdom teeth removed.You might be hearing noises and your brain is interpreting them as human voices.I humm or something make my own noises to myself,it helps me.
I also thought people heard my thoughts.What i did was give them something interesting to listen too.I study a lot about sciences,math, electrical engineering,thinking these noises were externally induced on me,so I wanted to learn about analog communications.Those voices cant keep up with me when I'm reading advanced math or something.Just cope with it the best I can I guess.Do mantain a sense a humor about it.I understand my lack of relevance.
I finally got help,doctor put me on risperdal.It helped to almost eleminate the voices but had terrible side effects.Now taking geodon with not much problems.The biggest problem is remembering all the pscho pain and some physical that I went through.
Get help from a professional early please.Went 25 years before I got help.Not a good thing.
