loner? (10 points for best answer)?

Am I a loner? or is there a better term for it? I am 26 year's old and as the years go by it seems i lose more and more friends simply because i am tired of hanging out with people. I spend all my time trying to "educate" myself through college, co-workers who are "smarter" than I in my field (Systems and network security). and Reading book's.

I blow all my money on upgrading the technology in my house. Just so i can enjoy being at home "alone" more. I could care less about getting a g/f because of the annoyance of having to deal with someone 24/7. Do i have some sort of psychological disorder? Even when i do hang out with friend's EX: a restaurant all i can think about is how much other patrons are annoying me.

I constantly have what few friend's i do have trying to set me up on blind date's just for me to say "F*k it 24 hours before the date. I don't know if i should be seeking a psychologist for some sort of mental problem or if preferring NOT to have to deal with anyone at all, except for going to work to survive could be considered normal. I just got my masters in systems network and security and now I'm already looking for my 2nd computer science field to get a masters in, perhaps data base specialist or networking admin). but I'm rambling at this point. Any useful analysis of my situation is appreciated.
