Hi Man, glad you're here. Hope you find some peace.
I'll certainly pray for you; if you repent and turn back to the Lord he'll forgive you and welcome you home. He may be teaching you some hard lessons for your own good right now; hopefully you'll learn from them. I don't know what kind of sin you're struggling with. Sometimes if we're caught in some sin and have lost control of it, extreme measures may be required to get free of it. He'll help you if you lean on Him and trust Him.
God bless.
