I need help!!

Hi everyone this is my first time posting. I need help in 2017 I had my daughter and gained weight but lost all but 10 pounds out of like 35 which I was okay with but I did allot of dieting but lately I have stopped and started eating bad and gained 10 pounds back 🤦🏼‍♀️ I used to do keto but after doing keto like any keto foods now absolutely disgust me like I can barely eat eggs anymore or pork or fatty things any other dieting i try I just cant stick to it. My minds set to eat good I wake up eat a healthy breakfast then all the sudden I want a snack or see junk food and its like someone flicks a switch in my mind and Im like I dont really want to loose weight I'm going to eat it Idc. Then I'm left with regret and upset about why did I eat it why couldnt I stay strong. I used to be really good at this dieting thing. Now I feel like I can't even control myself and I'll never be able to get back on track no matter how hard I try. Once I want a snack or see someone eat something or see junk food I need it and my mind says you dont need to loose weight your fine just eat it. I dont get it. (sorry if this is a little confusing)
