Its a good post. But not like its a simple decision " Ok, from now on I am gonna be strong , not gonna care thing that is not in my control, be gratefull with what I have in my life instead of feeling sorry for what I think i deserve etc."

It is a process to go trough to have that kind of strenght. And it happens with practice, starting from small things and pass it on to bigger decisions.

I think it would be good for you to write about how to gain that mental strenght for people are with zero confidence at the very bottom down.
