I understand ....I've been exactly here you are now 5 yrs ago when I made my goal weight.... and it does stink!!

It'd be useful for you now to journal about all these feelings you are having because IMO, they are totally normal. It does change and you will make new friends who know you now.
You've done an amazing thing for your self and your life....never forget that! Don't let their misguided reactions to your new body fool you.

I know it can hurt but it comes with the territory.
