I lost my virginity and I hate myself.

My boyfriend and I have been dating for almost 3 years. We are both Christians and we do plan on getting engaged this year. We messed up and had sex together. We both regret it. It happened more than once and I knew it was wrong but it still happened. I absolutely hate myself and I feel like I’m so far from God. I asked for forgiveness but I feel so guilty and I can’t make the feeling to go away.

Once I repent and not sin, I feel really good about myself and super close to God. But Then i screw up again. It’s like the devil is ready to attack me right when I get close to God...

What should I do?
