Have to win this battle

how do I get rid of the pain when pain just keeps on coming back it's like I'm trying to get rid of it but it keeps sneaking back up I feel like it's nothing but the devil trying to bring me down I have to prove him wrong to be stronger and smart I can't let him get the best of me cuz if he gets the best of me he's going to win this battle but the battles not mine its the Lords so I'm putting everything in God's hand and let him take control of my life because it seems like I can never win this battle
