Breaking Point!

I have a question to ask....why is it that when you are a kind hearted person there are major consequences, for instance when you cant be there to help out anymore now you are stamped a horrid person. I have been supporting two people besides my son and I for some time now. My boyfriend is disabled and waiting for his disability, I don't mind being there for him. A old friend of mine is homeless and unemployed and he is staying with us, i want to be there for these two loved people in my life. I have been forced into early retirement due to me being sick, my budget is basically non existent. i am doing what i can. There is a breaking point though food is flying out of the pantry for instance a box of cereal went in 2 days and i never had 1 bowl, lunch meat vanished in 2 days along with 2 loafs of bread. I have to support my son and take care of myself...i spend over 200.00 a month in doctor bills for myself. i have gotten to my breaking point, but if i open my mouth i am scared it is going to ruin my friendships. Gosh don't even get me started on the cigarette situation 4 packs are gone in 2 days. But here i am making sure everyone under my roof is fed and has cigs. I just want to know when someone like me will have the same kind of kind heart to be there for me, like right now. I am falling apart from the stress of the bills stacking up and the fact i am supporting 4 people all by my lonesome. I am very unhappy.
