Embarrassed

Hi ladies I have an issue but I'm not really sure where to turn or what to do. My issue is that I am constantly hungry I literally never feel full. I could eat a huge meal and still want to eat more. I am at the heaviest weight I have ever been in my life. I try to eat healthy and exercise but how do you control your weight when you never feel satisfied or full. I am so embarrassed I don't know what to do. Please no judgmental comments I just need some advice. I'm honestly scared ;(
