Hi, I’m not a Christian. But I always thought about this one thing. How can God forgive me for a sin I committed?

I have committed a lot of sins and mistakes in my life. Especially with regards to women and myself. I only recently overcame my P*rn Addiction and have been free of it for past 1 year. But also been to prostitution within this past year. I had never done it ever and I used to think I’ll never be one of those. But I don’t want to do that anymore. I always think of good and bad on the basis of what god will feel. But no matter what the bible says I am unable to believe that god will forgive me. I have this feeling that god will punish me when time comes and I’m just waiting for the inevitable doom.
