I feel exactly the same way. I don't know if it's that I'm lazy as much as that I really don't have any ambition. It's pretty hard to convince yourself to work hard when you're not really working for any particular reason. If you don't care for the reward, then doing the work required to get it just seems pretty pointless.
Same situation with the girlfriend, but I really don't care about that. I have no desire for sex, and relationships just seem like a huge pain in the ass to me.
Unfortunatly, I don't really have my parents to fall back upon, and I really envy those here who can live unemployed with their parents without it really being an issue. If college dosn't go well, I could always go find a job with odd hours (working night shifts has always seemed preferable to me) and/or requiring little contact with others.
