I just want you to know that no matter what, God will NEVER let you down. It has NOTHING to do with feelings. It has to do with what God has promised in His Word. Even if you wander away, He will NEVER leave you or forsake you.
Just in case you've forgotten, you are a precious child of your Heavenly Father. Jesus is your brother - He is the One who pleads with the Father on your behalf. If you HAVE done wrong, remember that God will forgive you. "If we confess our sins He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." I Jn 1:9. As far away as the east is from the west, that is how far He has removed our sins from us. Forgive yourself too. Rest in Him. Thou wilt keep him in perfect peace whose mind is stayed on Thee, for he trusteth in Thee.
Smile, Jesus loves you.
