Dealing with the Voice in My Head That Makes Me Feel Bad for Eating

helooo. how do you all deal with the voice in your head that always make you feel bad for eating and is always there telling you "why did you eat that?" "do you know how many calories was in that?" a bit of my back story: I struggled with a life threatening case of anorexia when i was a bit younger. Today I'm at a much better weight, and health, but I still struggle with some of the same problems and haven't figured how to deal with them on my own. every time i eat i immediately regret it and hate myself for it. whenever I even think about eating i start to feel like I'm gaining weight ( I know weird) in the past this would make starve myself and not even drink water, thankfully this doesn't happen anymore but that voice is still there. if anyone could share any tips & methods they use to not think this way would be greatly appreciated. <3
