I'm sad and just need to vent, I'll be ok

When I was fat i never got to hear the end of it, especially from my family.
"You need to watch your weight"
"Are you really going to eat ALL of that?"
"It's unhealthy"
Etc.

Now when I've lost a significant amount of weight I get praised.
"Oh you're so good with your diet and exercise"
"Must feel great to get that weight off"
"You look so much better now"

But what people don't know is that I'm even more unhealthy now, because I don't eat...
I'm too scared to eat, people kept judging me for eating, so now i just don't. I'm barely hungry anymore. No one notices that I don't eat, but they sure as hell noticed when I did eat.
I've got zero energy to do anything, I go to work and then I sleep, that's it.

I've got 2 kids and a husband and I feel so alone.
My kids hate me because I'm exhausted all the time and my husband has never paid attention to me, can't even remember the last time we hugged.

I want to show my parents what they've caused.
