How to make a bad Valentine's Day good?

Madeleine • Happily married to my husband, Samuel! We love adventures and living life together
So I adore my husband, we've been married for a month now and it's been absolutely lovely. I've been asking him to buy me lingerie since our wedding and he finally did. It was my v day present and it is beautiful. However, it's an extra large, and I'm a medium. Normally it wouldn't bug me but I've been really struggling with my weight and just feeling fat and lazy recently so it really hurt which is not how he meant it at all. I have big boobs and he meant to get something that fit those. I just feel so emotional about it and I'm not mad at him I just don't know how to get out of this funk and make our first valentines day better?
