Scared of going to hell? ?

I'm getting all caught up in swearing, I heard it was a sin, and I'm wondering if it is. It's just one of those things where I wish God would just tell me if it is or not cuz us humans just can't figure out if it is or not. I feel like I'm damned, even though I try to follow the commandments, which I think I do a pretty good job of doing, and I believe Jesus is the Messiah and my savior. Can someone bring some peace to me? I like swearing, I don't know if I can give it up, but I don't want to upset God by doing it if it is wrong.
