I've been in your situation all the way to the accident. You take a deep breath and you look deep inside yourself to find the answer.
Make small goals and accomplish them. Don't make excuses why you can't do something just make it happen even if that means living where you never wanted to or working at day labor. Don't rely on your family for nothing from my experience that amounts to a lump of shit. I believe you can do it by asking for help here you know your in a bad time in your life. Stop and find a restarting point make small goals and you will be ok you might even be better.
I had lost my home, everything I owned, and had nothing to show for it except 50,000.00 dollars in debt and a backpack of clothes. I went from a good job to a bus boy making 250 dallars a week. Now my debt is gone and i'm back on top. Better than I was. Remember every time you have to pick yourself up your that much stronger
