This may sound weird, but it almost sounded like she was projecting her thoughts about herself & weightloss onto you. Because everything she said about you could have been said about her self. I’m sure her parents tell her the same thing. This doesn’t make what she said okay, or how your friends reacted, ‘okay’... But I’m 23 now and still stutter (f) and I shit you not, you just end up not caring what people think, because it’s your life and you’ve gotta make it as good as you can. It’s so bomb that you can talk about it so freely though! Next time I would suggest not keeping quiet though. Voice your opinion in the same nonchalant manner that she did, like it’s no big deal but just how you actually feel. Your friends don’t give you the ‘okay’ to remain friends or remain welcome. It’s a joint affair. Two sides putting differences aside to be friends and make memories together. Be yourself 100% of the time, stutter and all. Don’t ever let someone steal your shine, or your strength or your confidence in yourself. (I’m not saying that she did, but if her way of speaking to you like this continues, stand up for yourself - it only proves that you have the respect that you’ve earned as a peer with your other friends who know you.) Idk. I hope I didn’t come off saying too much or in an assuming manner. Just wanted to shed light on your situation with some stuffs I’ve learned since high school.
