a brief snapshot. any ideas??

Hello all. Nice to be here.
I'm not sure what's wrong with me lately, but maybe I can et some input from some of you here. I have not quite been myself since the beginning of this year, and I have gotten progressively worse. I have began feeling very isolated from the rest of the human race. I have begun feeling like an outsider. ...Like I don't belong here on earth with everyone else. I've always been a loner, but have taken to spending more and more time by myself. I enjoy being alone. I prefer it to being with other people. Lately I have taken such a liking to my time alone that I have stopped talking with my acquaintances and spend all of my free time by myself. When I am not at work I stay home and avoid going out whenever possible. People make me extremely nervous. I find that when I have to talk to someone, whether it be at work, or on the street, I get this awful feeling. It's that feeling you get when every hair on your body stands up on end (even the hairs on top of your head!). This is not only with strangers, but also with people I would consider friends. Now just to clarify, I am not lonely, and I am not feeling sad or down. I am in my mid 20's, and my family has a history of depression. Both my father and younger brother were treated with prozak and zoloft. I never developed symptoms, and thus was never treated. Upon telling my parents what I have been feeling lately, they strongly suggested I go see a doctor, and get myself on an antidepressant. (one of my parents is a psychiatric nurse). They also suggested a healthy dose of social interaction. I'm open to the idea of medication, but It's unlikely that I will rush right out to meet new people and socialize, as it is one of the things I really really dread. I feel so detatched from the rest of the human race, I feel that relating to them is almost impossible for me anymore. I used to drink and used to party. I have stopped doing those things cold turkey months ago, so I am of a clean and sober mind. I just don't feel as though I can trust the people who i once considered to be my friends. My coworkers are concerned that I never have any stories to tell about hooking up with random strangers or drinking myself into a blind stupor on my weekends or evenings, and they think I need to "get a life". I just think it's pathetic that they believe that everyone has to live up to their expectations. I don't like sharing myself with everyone. I'm a very private person, and I feel that what I do is my own business. I'm just curious as to whether anybody has ever felt the same way as I have. I've kinda thought I may be developing schizoid pd or aggoraphobia. Anybody out there feel like they're really from another planet? Does anybody think I have depression? Any ideas? Any encouragement?

i have depression, and i can relate, and well, you may just be having some major changes in your life, and you've lost thinsg to hold onto, so you feel like everything is kinda seperateing itself from you, like you exist on another plane than everyone else, if you can relate, well thats depression for me, quite a bit, but i also have "psychtic features" that go along with my depression, so look out if you start seeing things of hearing things that nobody else sees or hears but you, when i get psychotic, it's simular to being a shizophrenic, so i hang out mostly at that forum, though this one is now holding much intrest, probably becasue i am no longer psychotic, so i am just depressed, sigh, well so yeah, i guess thats all i have to say, adn seeing a theripist can always help, never hurt, becasue all you do is talk and talk and talk about what you hate about yourself, life, and everyone else, and they just listen, it always gives me an euphoric feeling, better than being high:) well, good luck, and goodnight
