Just need reassurance without criticism 😕

This is my second pregnancy and all I want to do all day is eat, and not like fruit and veggies, but pasta and candy and all the snacks things! I only crave pop while I’m pregnant, but I just feel like a monster. Every night I lay in bed frustrated with myself and I just can’t help but think about the harm I’m doing my baby by eating all this junk, but the cycle repeats each day. It’s not like I go crazy, but I definitely just eat more bad than I do good. I just feel stuck in this cycle but the good food is just not appealing to me at all. I’m 19.5 weeks along, and it’s been happening for the past 3 ish weeks now. I don’t know if it’s stress eating, or boredom, I don’t know what it is, but I just keep snacking all day
