Although people are quick judge, yes that is always true but people are quick to judge with anything you do. I didn't tell my friends for a while and it was eating me up inside so I told them and they took it pretty well. There were some who didn't take it well and there were some who said they would support me no matter what and there were some of my friends who were scared for me.
After I told my friends I felt a bit of regret because yes, I felt like they were judging but I realized there is nothing I can do so I just went with it. Tell you friends the truth, but if strangers ask just tell them you went on a diet and exercise and you're not lying about it either.
