becoming bulemic and embarrassed

I am embarrassed to even type this out as I am a grown woman and a mother.
I had a baby a couple months back, i go to the gym 6-7 days a week religiously and try to eat clean.
I've never been obese or fat but always "thick" after my children. I'm 5'2" 140 lbs. keep in mind I do have a lot of muscle. 
Well after I eat lately I feel so guilty to the point where I think I make myself feel sick to where I vomit. I calorie count and carb count and I just have this image of how I want to look in my head. 
I'm scared I am slowly becoming bulemic. Or have an eating disorder. It's never been who I am or ever something that crossed my mind. 
but after I vomit I think ok.. less calorie and less carbs.
Has anyone been through this and have advice?
I'm actually very embarrassed and am writing anonymous because it's not a good feeling 🙄
