My advice? Go to the doctor. Stat. Gradual aphasia like that sounds like it could be some kind of serious health issue. Alternately, it may be some kind of mental block you need to work through in therapy.

As for jobs, there are part-time jobs that give health benefits. Look around. Some make you wait a year (see my grocery job), but you will get benefits. Also, you currently live in MA, the state where insurance is mandatory and subsidized for the broke. You will have coverage of *some* kind.
