my feeling is if you are questioning if you need to support yourself, chances are you need to do more. at 26 you should be able to pull in some $$.. while your illness might hold you back some, it seems your jobs don't add up to enough to support you even close to full time. making $5/essay i.sn't even really worth the effort, unless there are many hours involved, but even then that is below minimum wage standards here.

I would look for more steady and higher paying employment, even if only part time. this is the age where you need to start developing a base of support, both wage wise and contacts. it seems like you are missing those. if you love your field , search for more positions to fill in the blanks.

good luck!
