Caregiver Stress - My life is flashing before my eyes, I'm trapped!!!

I'm 23 years old and have been caring for my father in law for 2 years. He had my husband very late in life and if 82 years old. At first I knew it was the right thing to do so i just dealt with it, it was suppose to be temporary because he just had diabetic foot ulcers.

But then as the months went on it was apparent that he was never going to recover. He can barely walk and can hardly lift his cup to drink. The hard part is he has no serious illness and is all there in the head. This is a good thing but at the same time he constantly tells me how he doesn't need me and that everything i do is so easy and nothing. My meals I make him are never good enough, nothing is ever good enough. I tell myself to suck it up and realize what he must be going through not being able to do anything for himself, but can't help but see my life flash before my eyes.

I can't do anything he has alienated himself from everyone in his life and i now see why nobody wants anything to do with him. My husbands brother hasn't come to visit in almost 30 years. And since there is no one else my husband and I have the sole task of taking care of him.

I am feeling very depressed because as my sole job is taking care of him i no longer feel any fulfillment, i am constantly being brought down.

Thankfully we can still leave him at his house which is a few doors down. I just have to be there from 9 till 7 and then he sleeps the rest of the time. But by the time i get to go home my husband has to sit there and calm me down and tell me I am worth it. I just wanted to write this down to vent because no one in my life can understand my parents don't even have to take care of there parents. Even my husband can go to work and escape for a little while, I'm trapped.
