Any of the folks on here will tell you we have all been in similar situations, and that life does turn around usually. There is a very fine line between having a good life and it going into the toilet sometimes.
I understand how you feel about having your wife carry the load for now, but that is what a marriage or relationship is all about sometimes. I had a heart attack about 20 years ago when I was only 43. I was ready to go back to work the next week but my then wife, who is an RN, told me no way. I was going to let my heart heal for 6 months or so.
She forced me to quit my job and sit home while she went back to work. I felt like not much of a man too, so I totally understand what you are going through. However, she probably saved my life by doing that. Your wife realizes that you have been a good provider and that this accident was not your idea. There are lots of guys out there who don't have a good work ethic and simply take from their mates.......you are better than that and she knows it.
What you can do to make it better is take all of the other stuff off of her for now. Keep the household chores and cooking done so that when she comes home all she has to do is unwind. I would sometimes have a hot bath drawn for my wife with some fruit and a glass of wine, just to let her know she was appreciated for what she was doing. Also, tell her exactly that. Let her know how you feel about her picking up the slack, and that this is only temporary.
As for your cars going, been there, done that too. You will get another one when your life comes back on track, and it will come back, believe me. I think downturns in our life are God's little way of letting us not get too big for our britches. Every once in a while he makes us grateful for what we have.
I could tell you stories about losing jobs, moving my family all over the country, not being able to find another job, etc etc. Yep, life can be VERY tough sometimes. The other thing is that if a person is very poor or very rich there is all kinds of stuff the Government does for them. But if you are middle class like most of us it doesn't do one d*** thing!
Maybe you should start looking into programs your State or City has to help out people who need to get a new start. There might be training or some other programs available.
Don't give up, you have lots of friends on here who are there to listen and try to help you. Plus, you always have to remember the old saying " I felt bad because I had no shoes until I saw a man who had no feet." This is very true. You have more going on for you than you realize, you have family and friends who care. Keep us posted please.
