Before I say anything, I just want to give you a hug

and my heartfelt congratulations on getting your life healthy and being there for you wife and kids. That is so wonderful.
Jesus told us that his yoke is light.
At that time Jesus said, "I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children. Yes, Father, for this was your good pleasure.
"All things have been committed to me by my Father. No one knows the Son except the Father, and no one knows the Father except the Son and those to whom the Son chooses to reveal him.
"Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light." (-- Matthew 11:25-30, NIV)
I love those verses! Jesus is showing us that he does want us to be yoked under his Lordship, yet what he requires is going to be restful and and feel easy and light to us. I believe that the reason this is true is because he always teaches us according to our personal needs and our abilities at the time. God does all the work and he holds us up as he does that work.
Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us. Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God. Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart. (-- Hebrews 12:1-3)
To me that's fascinating. What is heavy and burdensome is the sin and stuff in our old sinful nature that drags us down, and sometimes even the opposition from other people. But we know that Jesus is the "author and perfecter of our faith"! So we don't have to do anything other than cast ourselves on Him. You are right about feeling that God helped you years before your acceptance of Him. God knew us and loved us before we were through with trying to do it our way. "We love because he first loved us." (1 John 4:19, NIV)
So now that I've said all that, and I feel more confident that what I tell you next won't be taken as a burdensome thing, I wanted to mention that perhaps you could be benefited by studying a little in the bible concerning being born again. Because the reason we can have rest and peace and joy and love (and be confident that our sins are forgiven) is because we have died to our old sin nature when we repent and believe and rely on Jesus Christ completely. That's what it means to be born again. Your old nature dies.
But on the other hand, I think it's natural for us to have a long memory when it concerns our past and the things we regret. One thing that helped me understand the concept of sin was to realize that when I believe and repent and am born again, I am justified through the blood of Christ so that God doesn't count my sins against me. They say that the Father actually doesn't remember our sins since he accounts us righteous through our faith in Christ. But that doesn't mean that we suddenly develop memory loss and forget the past. But it doesn't matter what we think of ourselves because we know that only the opinion of God matters. With some time spent with him, I believe he will build you up in your new life. After many years of walking with Christ, St. Paul said:
Now it is required that those who have been given a trust must prove faithful. I care very little if I am judged by you or by any human court; indeed, I do not even judge myself. My conscience is clear, but that does not make me innocent. It is the Lord who judges me.
(--1 Corinthians 4:2-4, NIV)
Keep in mind that St. Paul persecuted Christians! He participated in the stoning of St. Stephen by looking on and approving the stoning. He also hunted Christians down so mercilessly that he was on the road to Damascus to hunt them in a foreign land. So he was so committed to doing evil to the Christians that he would travel really far to do it. And in the middle of this sinful plan, the Lord met with him and literally changed him from his old corrupt nature to the man we know and love as an apostle. So knowing that, you read his words I quoted above about not judging himself, and it's remarkable. God is amazing. It's also interesting how Paul says "My conscience is clear, but thta does not make me innocent." No indeed. A guilty man can feel as innocent as a baby. And an innocent man can feel horribly guilty. But in faith, we know that we need Christ because of our sin nature and our weaknesses, and when we rely on Him fully, we are blessed.
But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me. That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.
(-- 2 Corinthians 12:9-10, NIV)
All these great truths concerning being born again are things that the Holy Spirit can and will reveal to you. Spend time with Jesus in prayer and reading your bible, and you will find great peace and rest in the certainty of God's promises to you. God bless you.
2 Corinthians 5:17 "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new."
