Lost my job

Ever since I lost my job 5 years ago, due to poor health for that matter, livelihood has been tough for me. I feel lonely too because my wife has left me 3 years ago and I don't blame her for her action. Once in a while, she visits me or I visit her, as a friend. I do miss the good times I had with her. I'm not sure what's the reason for my poor health. I just now I get tired easily and sometimes I feel that my legs don't have energy to carry me around. It's just so exasperating if you have a life like that. Doctors I consulted have not been able to help much too plus the fact that the money I need to pay the docs is big amount and I might as well use that to pay for my living expenses.
