I know you find that you struggle a lot, with many things, with all the things that you wish you could fix about yourself. We all do. Whether you want to have more patience with your children, want to be joyful and peaceful all the time, want to be more organized, want to have more discipline in any area of your life, want to be more Christlike, and the list goes on....
I find comfort in this. ..
"But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong; 28 God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, 29 so that no human being  might boast in the presence of God. 30 And because of him  you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption, 31 so that, as it is written, “Let the one who boasts, boast in the Lord.” 1 Corinthians 1: 27 - 31.
I am foolish and weak. Sometimes I feel like a "not". There are so many things about me that I wish were better.
2 Corinthians 12:9 "And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."
He accepts me and uses me as I am. My weakness allows His strength to shine and makes me grateful to Him that He will use me just as I am. He takes what I am and makes it beautiful.
Rest in Him. Look to Him. Don't strive so hard.
