Hey Bud..I feel ya ..I have been on top of the mountain and I have been to the deepest darkest holes....It will get better, just stay positive ,keep the faith and all will be good again before you know it Besides if your at rock bottom ..the only way to go is up....
Hang in there, times will get better. It sounds like you are a real man to give up your superficial things to help the man that raised you. I just fought and beat cancer over the last three years and had to sell my house and alot of my stuff to get by, but with prayers of friends and family we are starting to climb back and even got me another project car. I will pray for you and your family and may GOD look after and protect you until you are back on your feet.
