By no means am I suggesting that losing a parent law is as hard as losing your actual parents but if you were close to your in laws it's hard
You have to be strong for your kids (their beloved grandparents) and your partner of course. But you yourself can feel like you're falling apart sometimes. You don't get included in the sibling support network so you can feel lonely
I suppose a lot of people don't give a stuff about their in laws but mine were like parents to me as I was orphaned young.
My mother in law has weeks left and we only lost my FIL one year ago. I don't want to pity myself it's awful for my DH and his siblings. But I'm not sure I have the strength this time
