First of all, welcome.
It sounds like you need to get a few things sorted out with symptom management, but the other thing is, from a personal development, independence, and income standpoint, education and employment is going to be critical. I would explore your options with regards to jobs that you can do from home. For example, I am in the medical field, and I know former teammates that have gotten out of the inpatient world and now work for insurance companies, medical supply companies, medical records, and other related areas that the employer will pay for the high-speed internet connection and computer and have you work from home. I am quite sure, other fields have folks that work from home, as well. When I say this, to be more specific, don't sell yourself short by trying to do a "small home business" that will only supplement income. I am talking about a legitimate, well-paying job with benefits.
Not all of us can deal with people, face-to-face, with complaints and emotions, the masking we have to do, etc. but something a bit "separated" is often manageable. Migraines can be awful. My wife has tried every experimental drug on the market, and not on the market, and still no relief, MRI changes, blurred vision, aura, "the whole spectrum", but she fights through it as an RN running an outpatient clinic. I don't know how she does it. That said, if you are at home, comfortable, in a more relaxed environment, sitting in front of a company computer may be more for you.
Something to consider.
