Weight loss pros & cons

I have went from 186 to 138!!! Huge amount of weight loss & steady losing. I haven't done this by choice however it's because of my gall stones and gastritis which create gall bladder flare ups or gastritis flare ups that cause the horrific vomiting episodes. Anyone else go thru this?

Pros- everyone loves losing weight!

Cons- people give dirty looks & judge me because I'm so small for my height. And it makes me uncomfortable and not confident. How do you find that confidence being so small & what do you eat to maintain it?
