Struggling with salvation

Hello. I started seeking God about a year ago and accepted Jesus as my lord and savior savior. I confessed every sin I could think of and have done my best to turn from them since. I understand that God has given us grace, but I struggle with still feeling like I am not forgiven. I feel guilty.m for feeling this way because I know it means I’m not fully accepting the gift of grace. I truly don’t want to think and feel this way. My biggest hang up is my past sexual sins. Before turning to Christ, I had a lot of sexual partners when in my act of addiction to alcohol. Now I have two children by two different fathers. I am engaged to my youngest father and we do not have intercourse anymore. I don’t want to until we are married. We sleep in the same bed though because we do not have extra beds. I just struggle with this a lot because of my situation. I tell myself there’s no way God could forgive me for my life and I know it’s wrong to think this. Any advice as to what has helped anyone else’s who struggled with similar issues with salvation? Thank you
