Eating disorder?

Hi guys I’m 20 and I have a question..

Do I have a eating disorder or should I go to the doctor and see what he says?

Every since I got out of an abusive relationship with my kids, I have found myself to become very depressed. I work sleep and take care of my kids around the clock. I’m doing one of those 3 things and nothing else. Well here recently I have started talking to this guy (he’s amazin) and he thinks I might have an eating disorder 🤔

I will only eat once a day and it be something small like 3-5 potato wedges or a slice of pizza. I drink through out the day but im just never hungry or I forget to eat (as crazy as it sounds) please comment advice or anything you may have to add
