It's not too late to set things right and be put right. "Unforgivable" you ARE forgivable.
A Psalm of David. The LORD [is] my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters. He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou [art] with me; thy rod and thy staff they comfort me. Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever. (Psalms 23:1-6, Eng KJV )
May the Lord heal you of depression and guilt by filling you with His Spirit; forgiveness and joy taking up permanent residence.
The sacrifices of God [are] a broken spirit: a broken and a contrite heart, O God, thou wilt not despise. (Psalms 51:17, Eng KJV)
You now need to be proactive by accepting the Lord's mercy and moving forward to do whatever you think it will take to win the forgiveness of those individuals that are upset with you, and get your nervous system back in shape, because it may be shattered by stress.
May the Good Lord that opens the door when we knock hearken to your knock today and grant you all that you wish for.
