Hi!
I fell too after 10 days sober but now I'm back again trying to live a sober life(3 days sober) and I'm extending a hand so you can join me too!
God wants us to try, and he can't give us the blessing of recovery if we give up trying! Remember that you're only human and that it's ok! God loves you very much and you are right, He doesn't make junk...EVER!
Just dust your dear self off and try again! We're behind you 100%!
