I am sad because there is nobody I can appoint as guardians if I die. I don't have a POA in place because I have nobody to put down for that.
Onlymee, why are you behaving as if siblings are the only people who are appointable as guardians? I have three, and none of them would be the guardians of DS if DH and I died -- no rift, but there are more suitable people whom we've nominated.
Actually, I've just read the rest of your post properly --
I saw 3 sisters in car park going round to one of their houses and burst into tears because I have no concept of what it must be like to be part of a family.
It is all a bit shit. If I had an only child I would not put them into any extra curricular activities because every man and his dog would be coming to tell me how spoilt my child was because I was forking out £2.10 for Brownies or whatever.
Subsequent children died. I wish I had too. I wish I had the courage to choose not to live.
It's clear you are profoundly depressed, and should get help for this, and that it's affecting your logic. I can understand feeling wistful at siblings getting along if you've never had any and idealise the sibling relationship, but it's definitely not a normal response to think that other people would see you sending your only child to Brownies as evidence of being spoilt. My only child goes to Beavers, and I can assure you that no one thinks we are spoiling him because we pay the (minimal) subscription -- it's not as if he's learning to ride unicorns on a gold saddle.
