My best friend gave birth 1 month after me and she has already lost all the pregnancy weight, whereas I still have 5kg left to go. She looks great and seems to be handling motherhood better than me overall. I am happy for her, but also a little resentful. Is this normal?

i lost my pregnancy weight of 6kg gain and another 6kg in a month or so, but i was feeling weak and hungry all the time. it wasn't a happy period though i was slim.. anyway in the year following i gained back to almost my usual weight. i do feel happier and healthier now.
