Getting your GED is something you should look into .... especially if you want to go to college ... I haven't tried getting into college for several years, but assume the requirements have only increased .... and in my day you had to have a hs diploma or a GED .... at least to attend and get credit for the classes ... you could however ask any comm college about attending a class or two without getting any credit ...

I didn't mention this the first time, cause from what I've read, I don't know that it would fall under what you have an interest in ... but you could check with local churches to see if they have any groups for those in your age range to meet and mingle ... ask some questions so they understand that you aren't necessarily interested in joining their church ...

Do you know a couple of people close by in your same age range ... maybe contact them and set up a monthly meet and greet with them and others they know .... have everyone invite at least two more people and see how many turn out for the first couple of times .... start out at a local park on a Saturday afternoon or something - pot luck. It may be that you would become the best guy around to a lot of people if there is no other socializing currently happening ... again, best of luck!
