cancer just wont quit even though it already took my wife from me

i dont no how much more i can put up with. im at the end of my rope. i knew the day cancer took my wife things were going to be so different in my life. cancer took the only one that i loved 6 months ago, yet it still reaks havoc in my life. i have no one, family and freinds were never there us at all and when they did stop by to say hello they would steal from me. i cant do this anymore, it has won in every way it can. i had to leave the house now. i couldnt afford it by my self. im now living in the car and have been for a week. the only thing people can say to me is you have to figure something out. I KNOW!!! if it were that easy i wouldnt be living at walmart parking lot.  i no people had to be in simular situation and found a way out. i tryed, i cant get no help from the county or any resourses because they say they are out of funds or im on a waiting list. i swear cancer is the whole reason this is happening and my future isnt looking to good. it mite just take another without even having it.
