possible psychotic disorder?

Hi, I'm a 19 year old male with what I consider to be significant mental health problems. My overall problem is that I can not function properly at school, work and social situations. Some days, going to the store to pick up a few items can be a difficult task for me. It's hard to explain but I get so many impulses that I end up acting weird and not completeing even a simple task such as shopping. In respose to this, I isolate myself as much as possible (also because I don't like people). Well anyways, I though I should list some of my symptoms in hopes that someone can give my some direction into the possible mental disorders I might have.

-significant decision making problems. My bad decision making has almost got me in several car accidents and always seems to cause probelms in social situations.

-aimless wondering and an extremely short attention span. My attention span is so short I often aimlessly wonder around the house. I do this everyday for a good portion of the day.

-poor speech. My responses to people are usually short and empty, I couldn't hold a conversation If my life depended on it. If I try to explain something complex it's very difficult and my speech gets scattered (typing this is difficult).

-extreme apathy and poor grip on reality. If someone close died, I don't know if I would even react to it very much.

-unpredictable hostility. I'm generally a laid back person but atleast several times a week I get into extremely hostile moods. I have no controll over it and I fear I might snap on some people (I have several times already).

-Feeling the I'm being monitored/watched that only seems to get worse and worse. People monitoring what I'm doing started off as mild but now it's starting to effect some of my behavior.

-Other symptoms: Several people have told me I never show emotion and I also have poor eye contact.

Well to sum it up I've come to the conclusion that I'm going to fail in life, and tha I'm never going to be able to hold friends or get married.

thanks for any input.

mmm... some of what you go through i can relate to
but for you to be sure you should see a psychologist
thay can tell you if it is a thought disturbance, chemical imbalance,
or even a stress reaction.. You should diagnos yourself
because there are many things that appear to be one thing and it really isn't so go get the info from proffessionals who know
cause they here your whole story..not just symptoms
