What happens when you can not eat regularly, for month's?

My family and i, have been threw the poorest time of our 21 yrs. together! I know other's can have it worse, my husband and i, have 2 daughter's, 16 & 13. He's been out of work for 5 month's, and when he has worked, it has to go on bills! ,But if we have money left there is ONLY enough to feed our daughter's. I went from 212 to 138, in a few month's. I feel awful, pretty much of the time, and can no longer eat, without stomach cramps and pain! My eyes are getting blurry, and my skin looks terrible!, my hair is falling out and we lost our insurance, and some how DO NOT qualify for assisstance, which we've never had in our life. I  have my own Enterior Designing business, but am sick in one way or another! This is not like me, i've never have been LAZY! My question is... Am i looking towards an early grave? Could my eyes, be leading to blindness?, and if i keep eating this way, (WHICH NO RELIEF IS IN THE FUTURE YET) how bad am i hurting my body?
