Help, i'm at my witts end?

ok...i'm a Brittle diabetic..with strokes,stress,depression, migraines,and one heart attack under my belt.. yet i'm not able to find help that doesn't cost me a fortune. i'm 44yrs old married and no kids. live with the parents that are in cridicle situations i take care of them while the wife works. i have my own business.. own and operated at the home. i cope with everything..and yet i feel like crap..games don't do the trick anymore..i'm a master rae-kae and even the relaxation of that has no internal help anymore. i'm at my wits end!. and yes i have been to doctors..but none so far have helped,. only to take my money!
