I feel bad for posting this here for all people struggling, but...

Since I moved out from my parents' house, I have lost 25 kg (55 lbs) since I moved out in late 2019. I guess it's a good thing since I'm now barely within the less-than-BMI-25 range but I also feel super guilty with a close friend of mine who is still in like her 33-35 range of BMI and the change is for sure noticeable appearance-wise, and she struggles a lot. How can I make her feel less bad about the whole weight-loss ordeal? She's like one of my best friends and I care a lot about her
