You can try to get a GED? You can get financial assistance for test prep. There should be some entry level jobs out there that won't care like @Zegers mentioned. Dishwasher would probably be an easy position to get (not as much human interaction). Gas station entails being alone in a shop, potentially being robbed, and generally dealing with some unsavory characters, but other than that it's just cashiering and some stocking. You could also try for bagger at a grocery store.
