Oh darling! As hypocritical as this sounds coming from someone to trying to change their body, please be content with what you have, enjoy it, celebrate it and treat it well.
I understand where your boyfriend is coming from. Mine does that too. But in the same retrospect, it is our body.
Sweetie, you are a size 1/2. You have nothing to be insecure about.
Honestly, to make me feel better about myself, I listen to music. There is always a somg to make you feel better.
Love Yourself, because as I, and probably many other people say, you are the only person who is going to be there in the end and through it all.
I’m not sure if any of this helps.
Alway here to talk. Xx
