@LuckyMoonstone I got home and I sobbed my eyes out in the bath for an hour!
I am happy for my colleague genuinely but it was so hard, only a very small handful of people knew about my situation (my manager and my 4x closest colleagues - and I only told them as the sickness hit me like a train and I didn't want them to think I was skiving in the bathroom!) and they've been wonderful but I think it's just seeing someone at the exact stage I should be makes it feel harder.
I feel selfish but I'm dreading watching her bump grow, see her going off on maternity and everything. She has her scan picture on her desk and it makes my heart hurt that I don't get to see what. But I know it'll be my time when it's right!
