Yeah, community colleges accept GED students. Over 90% of US schools do, in fact.
In my opinion, you can't overlook medical and dental insurance. I suggest getting a job with great benefits, like at UPS, even if the wages are a little less. Especially if you're going to community college soon, UPS has benefits packages with great insurance and even assistance in tuition.
If you can get your place close enough to a good benefits job like that, perfect. Hoof it and save on gasoline.
I did so for a couple of years.
If you haven't already done so, find apartment candidates and make practice budgets. You can't make too many of them, trying different things. You may need to fudge some estimates, but when you do, fudge a little high. If you end up being wrong, you can buy yourself something nice rather than owe somebody something.
