@aymanderz - I hesitated to reply to you because I don’t have ADHD and I know exactly nothing about what’s required for an MFA. But I know what it feels like to post questions and nobody responds. (I now have three sons in three different colleges, with one heading for graduate school, so I have asked a lot of questions on CC.)
FWIW, I worked full time as an attorney while working on my MBA and was very successful in the long run. However, the MBA program that I was in (Michigan) offered enough evening classes that it was possible to take classes two nights a week – fall, winter, and spring – and graduate in four years, instead of the normal two. Even so, this was not easy and my social life was pretty much non-existent. I had to drive 40 miles to Ann Arbor and 60 miles home and there were a lot of times when I was driving home on I-94 at 10:00 pm in the winter that I questioned my sanity. But I did not have kids at that time, so at least that was not an issue.
A friend of mine got both her MBA and a law degree in ten years while working full time as an accountant and with two kids at home. That seems impossible to me, but she did it. I worked with two other attorneys who had worked full time while going to law school nights. So I wouldn’t rule out what you want to do. One advantage you will have is that you should be much better at allocating your time efficiently compared to students who went right to graduate school from college. And you definitely seem to have the brainpower, even if it processes words a little differently than other brains.
Whatever you decide, good fortune to you!
