Grrrrrrrr

A friend phoned me up this morning in tears. She has been trying for a baby for quite some time and been enviably serene about it all but may have reached breaking point.
Her sister just told her she was pregnant and she found herself upset. I think what she was most upset about was being upset. She didn't want to have that reaction, she didn't want to be like that. She was happy for her sister. But also felt like it was unfair. She was older and she had been trying for ages. And the reminder hurt.
I tried to tell her she was allowed those feelings but I don't think I got through.
It makes me very angry that it is considered so unacceptable to have such feelings that people like us end up feeling like we are horrible and mean on top of everything else.
Grrrrrrr.
