This is such a good thing to remember! Listen, no one can see inside your clothes to read the size on the tag. Nobody knows if you're a size 8 or 10, a size 14 or 16. What matters, truly, is the good in your heart!
The ONLY time it should matter is if you don't feel good: if you're feeling sickly, or heavy, or your joints hurt. Then, yes, there may be a problem to which you can see a doctor or go to a gym or get a massage or whatever you think will make you feel better.
Just know, when people love you, they see YOU! They don't see that your clothes might be too tight. They don't see that your hair is thinner than before. They definitely don't see that extra wrinkle. You are loved!
