Yep that’s me. No resolve. Gaining weight again. Eating junk food. Sweets and Carbs. No control. Portions to big. Not exercising right. Muscles sore from any work. Depressed cause I want discipline my psych to do it. Praying for God’s help. No Help. Unanswered prayer. I think God is through with me on this issue cause I want listen. I need help. Inexpensive help. Eat to much and wrong foods. Everything I like is fattening. Down here all the food is good. I am constantly around good food. Ex-Church, relatives, wife, good cooks including myself. I made a jambalaya last Thursday to die for. So good I ate to much. This past weekend miserable cause around good food all weekend. This morning fellow walked in to office with fresh cinnamon rolls. Big ones. Good to the last lick. What am I going to do. Clothes getting to small. Knees hurt, Pre-diabetic. Depressed state of mind. And Look, I am a minister. I know Gods book. I know all the answers. Why can’t I just do it??? WHY WHY WHY!!!!!!!! HELP Somebody......I am desperate for some answers. Pray for me....Please!
