I don't have any donation, even not 1 cent

I don't know how to do with people to ask donation
Cheer up, you don't have to ask people for donation. How old are you? There's a lot of things that you can do and I believe it. We have our own skills that we can use for making great value for our time.
We know life sucks but we have to deal with it and to those that will give up are the real losers. I know it's a big pain to your mind and heart about that lost and it's hard to accept it up until this moment.
What you need to do is focus on your goals but first you have to move on mate, next pay those debts and lastly don't gamble again. Make your life beautiful, I'm sure you'll overcome this.
Just don't think about ending up your life.
