You are, you skinny narcissist! Lots of us have gained weight during the plague and are jealous of those who went the other way.

It sucks to lose someone who you used to invest time in over something so trivial, but keep doing what's best for you and your body no matter what people say.

I'm sorry that her discomfort with herself is getting in the way of your friendship. Continue to talk with her if you want, and if weight is ever discussed offer her any support she needs...When someone in your life makes a concerted effort to change it can cause others to react negatively. They're the ones stuck & there is a level of jealousy/envy/discouragement that is felt by those "left behind".

Nothing bothers people with problems than people who choose to change for the better, because change takes effort.
