Right, that sounds like a good plan. Moving out of the house needs to be step one, so here's how to go about it. Do you live in a city with City Search? Go to
http://www.citysearch.com and look for your city. Once there, search for "apartment finders" or "apartment locators", something like that. These services will help find a place in the area you want in a price range you specify, along with any extras like washer/sryer connects. These services are free for you because apartments actually pay a bounty to the appartment locators for finding you. I recommend against a random roomate, seems like that's just asking for trouble.
You need to do this today, seriously. If you can't use City Search, just look in the yellow pages. Get this taken care of and be moved in before the semester starts or you won't be able to do this.
Then, find out when those clubs have their first meetings and show up.
Lastly, my school has free psychiatric help for students (part of the health fee we pay). Yours may have that too, but like all these other things, you need to get signed up early.
