Struggling with an Eating Addiction: Need Advice

I've been struggling with this for a while but I just don't want to be made fun of so please be gentle with your words. I know it sounds stupid but I have an addiction to eating... no matter when it is, what it is, I don't care. I use it to cope, when Im bored or when I'm hungry I order way to much but eat it all even tho I know my body can't take it. I don't know how to make things at home because I don't even know where to start. I need to eat low carbs because my blood pressure gets too high from eating carbs. I'm currently 320lbs and I gained most of my weight in 2023 after my stepdad died. I just want my body, health, and happiness back. Any advice that isn't rude? please.
