Have you thought about just going to school part time? Instead of taking the full courses, you could take say half of them? It would take twice as long to get it done but if you can do it then it would still be worth it once you finished. I am still going to school and working full time and I don't have time or money to do the full amount of courses, so I am only taking a few at a time. It'll take me four years instead of two to finish but I will still get it done.

Other than that, I don't see why you can't do it. You definitely seem smart enough and to have already done what you've done, that's great. Not a whole lot of people can even get as far as you have. I think you can do it and I don't even know you. If you have to take the full course, then you just have to ask yourself if it's worth it. If it is, then I say GO FOR IT. We only live one life and we have to make the most of it, now is a good as time as ever to get started.

Wishing you the best,
