Please don't judge.

I'm a Christian lady. I have recently been struggling with impure thoughts and doings. I want to be better for God- i do. But every time I believe I am doing better the devil takes me down again. Sometimes I don't think God wants to help me.. Sometime I don't want to ask God for help because I'm embarrassed of the sins I've committed. I'm stuckright now. I need out of my wrong doings. But I feel like I've dug a hole even farther and don't have a way out. I hate myself for it. Idk how God can still love a sinner like me... How do I go to God about this? I know He is loving. But I'm scared and ashamed...
