NC here because I know I am being pathetic so this is more of a 'Why am I so pathetic' rather than AIBU.
My niece by marriage is 19, gorgeous, great figure, loads of friends, boyfriend, always out partying and loving uni life. I've been in her life since she was 12 (DH is her mum's brother).
I obviously care about her and she is a lovely girl but I can't help feeling a teeny bit sad and jealous. When I was her age I was overweight, wore glasses, didn't have many friends, had some minor health issues and still lived at home. I didn't have a proper boyfriend until well on into my 20s. I'm now very happily married to DH with DS and like to think I look quite nice and have good friends.
DH is close to his niece and they regularly chat on WhatsApp etc and he always shows me pictures she sends him of her ready to go for nights out. While I always say the right things, I can't help but feel sad that I didn't have her life at her age. I feel sometimes as though I missed out on so much in my teens and early 20s.
I just need to give myself a shake, be grateful for what I have and actually be thankful i'm not her age again, don't I?
