Growing up, my parents never thought much of me. Turns out they were right, I didn't amount to shit. So remember if you feel there is a glimmer of hope for your life- there ain't. You ain't shit and you ain't never gonna be shit.
Every human life at conception has value . It's what you decide to do with it, that matters. If you messed up everything, start over right now. It's never too late to make things better. It may take time to see results but fight the good fight. Anyone is capable of making things better.
If you have lost all hope talk to a priest (orthodox preferably) with a good reputation. But any priest worth thier Salt, in any of the main denominations can help you.
