Hello imnotsurewhatimdoin: Welcome to PsychCentral! From what you wrote, it sounds to me as though you're having some difficulty adjusting to a still fairly new school environment, being that you transferred. I recall reading an article in our local newspaper recently which talked about this being quite a common problem among college students. It is certainly unfortunate that you are living in a drug fueled environment. Is there no way to get away from that?
It sounds to me as though you are experiencing some situational depression... that is depression that is brought on by a particular set of circumstances... as opposed to the type of depression that is with a person all the time regardless of their circumstances. So the good news is that if you can change your circumstances, your depression will likely dissolve.
My perspective is that people become friends because they share common interests. So my thinking is that one way for a person to find friends would be to become involved in activities where like-minded persons are likely to be found such as clubs, volunteer organizations, etc. This not only creates an opportunity to meet like-minded persons, but it also provides opportunities to simply have things to do that are of interest & possibly be of help to others. Serving the needs of others is, I believe, a pretty-much proven method of reducing depression.
Good luck... & please keep posting!
