If you felt like I do what do you think you would do...?

I am a Male 6'2" 240 lbs. who is developing a breathing problem from smoking for about 12 years. I do my own thing landscaping, about 8 lawns a week all with a 21" push mower. I am alway's lacking motivation, energy, and have no goals. I just strive to survive. I am married of 9 years with two boy's ages 13 and 9, and my wife really doesn't do much of anything but lay around in bed and suffered from a minor head trauma when CVS Pharmacy gave her the wrong med's for pain, and she was illergic to 750 Vicadin's when she passed out and hit her head, but she acts and thinks like a child most of the time I think. She's 34 and I'm 35 and both of us are on disability. Her for being Physically unable to work, and me due to Having ADD and Emphasima and Huntingston Disease. So what should I do the rest of my life besides being stressed out all the time, and trying to do **** to make money when I feel like passing out after 4-5 hours. of doing anything...?

Well.........you really have it piled on! Have you been diagnosed as having Huntington's or is it just because it's in your family?
I would if I lived in your shoes, quit smoking, find an easier job. Anythings easier than a push mower. Spend quality time with your kids and your wife and do things one thing at a time. Make a list and mark off each thing as you do them. Keep a schedule of yours and every body's life and stick to it. See a Dr. regularly. Rest when you need too. Kids can be a tremendous help when you need them.
If caring for your wife is too much, check out home-care agencies in your area or possible placement in a nursing/rehab establishment. You have too much on you plate for someone with your health conditions. Don't you think your children deserve to have you around for as long as they can since your wife is so disabled? Take care and good luck!
