Is it too late for me?

I grew up in the church my whole life. Growing up I was close to God and was a good kid. As I got into my twenties I strayed from God. I started doubting God’s existence and stopped following his commands. I never really reconnected completely with God. As I got older my faith got stronger but I wouldn’t say He was a priority in my life. When I was in my twenties I made a mistake. I don’t want to go into details. I feel like I’m at the end of my rope and full of regret, shame, guilt, anxiety, and horribly depressed. I’ve been reading the Bible and praying all the time. I wish I had never strayed and stayed in Gods word. I would love to live a life glorifying God and turn my life completely around. I have asked God for forgiveness for my sins. I believe He has forgiven me but I still must live with the consequences of my actions. I honestly don’t think I can keep going. I have been heavily considering suicide. I know that suicide is a sin though. Is it too late for me?
