Do you know the Disney Movie "Meet the Robinsons" and there's a famous quote that walt disney says "Keep Moving Forward"

That quote very applicable in lives right now.
That's what God is also telling us in the book Isaiah 43:18-19

“Forget the former things;
    do not dwell on the past.
19 See, I am doing a new thing!
    Now it springs up; do you not perceive it?
I am making a way in the wilderness
    and streams in the wasteland.

The Lord says do not dwell in the past, forget the former things because He is making a new way in your life.

How is He gonna show His path, His plans for us if we keep on dwelling in the past? If we always doubting ourselves saying you are not enough, you are not worth it... Well guess what? God loves you! He doesn't care about who you are in the past because God said in Jeremiah 31:3 "The Lord appeared to us in the past, saying: “I have loved you with an everlasting love; I have drawn you with unfailing kindness."

You gotta let go, you gotta surrender all your problems to the Lord as He says in Matthew 11:28 "“Come to me, all you who are weary and burdened, and I will give you rest."
We gotta let go and let God come into our life and let Him do His will for us.
God loves you, God will forgive you! don't forget to forgive yourself.
