If you really want to get out of school quickly, get one of your other majors as your BA assuming you are further along and then go to graduate school for social work. Both psych and education are good precursors to social work. Tell your advisor you want to graduate quickly and that there is good overlap with your three interests and you want help figuring out how to graduate quickly with the idea that social work will be your graduate degree. Buy a cheap, old bike and a way to lock it up. I say buy a cheap old bike for two reasons: people steal bikes and you sound like funds might be an issue. Find the nearest quiet hangout spot: the library, some place in the student union, some study area set aside in the dorm, and use it for quiet alone time. You could listen to music on headphones and study, read or write, or draw or knit, or just sit and chill. Investigate when and where you could move to elsewhere in the dorm that offers you more space.
