Please whoever reads this I need prayer. I struggle with substance abuse. Have since I was fourteen. I know that it’s a choice I dont want sympathy, I want to change. so badly but I just can’t seem to beat it for more then a month or so. Ive talked with people at my church about it. Been to rehab. I thought I had it beat but the relapses keep coming and I don’t know what else to do..I want my joy and peace back that i have when I walk with god
