Inundated in guilt and grief

I have so much to be regretful for, but mostly, forgetting to pray and give thanks when things are going well. Now, my son needs my help and OUR prayers, (yours and mine), but this unforgiveness toward myself, I feel is blocking true communication with God - and it’s a cycle, because I then get even sadder, guiltier, more depressed and feel further removed from him. I pray for our HOLY GOD to send his mighty and ministering angels to me and my son and to show us his mercy and love. I am not perfect, but I wish to be in his eyes. I need him to make me whole. Amen
