I Need to Stop Eating That Much

Have you ever eaten so much that u feel like ur punishing urself but tou dont know y? Thats how i am right now. I work pretty hard and iam the only one in my dept. So i take a lot of "i need this" "this has to be done right now" and a lot of stress. I usually dont eat during the day cause it makes me sluggish and sleepy but i work outside and on my feet all day. Sometimes up to 12 hrs. I walk 2 miles a day and somerimes on the weekend but when i get home i drink a lot of water and tea and i eat a lot. I get so full i feel like iam going to pop but i just canr stop! Iam beating myself up inside and punishment and for what! I dont know. I can feel the inner me screaming "stop! Dont do this to urself! You need to get this under control. Please stop!" I dont know whats wrong, i dont know how to stop, i just dont know.😔
