You are depending on you too much. Afraid to fall because you feel it is determined by you following all the rules and getting everything right and not slipping up and making sure you did this and that and the other and didn't make a mistake and....
I've been here, and many times. The answer, the only one I have at least...
-------Let go-------
It's a relationship with God the Son, Lord Jesus. Not a daily test, or an obstacle course, or a set of rules that depends on us.
Yes, you will make mistakes.. But we don't keep our children locked up in a room their whole life to keep them from making mistakes, we simply love them and help them as they go.
This is what God does, and He isn't going to love you less, or pull away from you, or change on you. He loves us first. (John 6:37) (1 John 4:19) (John 15:13)
Lean on Jesus.
Trust in Jesus.
Give it to Jesus.
Let go and live and trust He will help you with living life.
If you are doubting at all, it is doubting God will still love you if you slip up.
He will ALWAYS ALWAYS ALWAYS ALWAYS ALWAYS ALWAYS love you!
Even if you do everything you just listed and do it all just as wrong as you possibly could.
Your heart is to do good and follow Lord Jesus, and I can clearly see that in your post. This means that God sees this also, and He doesn't want you afraid He will stop loving you, or that you'll commit every sin in the book. Stay sharp while trusting Him but don't let fear hold you down. Fear is a control mechanism. Love conquers fear. (Ephesians 2:9) (2 Timothy 1:7) (1 John 4:18)
God wants you to be His child, not His robot, or tool, or slave for just work and serving.... He loves us.
Just like the three year old trusts his or her parent... so God asks that of us, and nothing more. (Matthew 18:3)
Am praying for you.
Remember how much He loves you! (Romans 8:32)
