can you develop a skill? you seem pretty smart. for example, maybe you are good with computers? this can lead to a temp job, and then a real job. IT doesn't care much about fancy degrees and you'll find lots of shy people in these departments.

can you join a church or other group? this will lead to some socializing that improves your comfort level with others.

can you make a friend with an outcast? like someone who will overlook your nervousness and just be happy to have a friend? sounds lame, but it will make u feel good. it could even be volunteering in a shelter or old age home

if you can do any of these things DO THEM NOW! the one sure thing is that time marches only in one direction...
