Why is it so sad?

Re

13 months ttc no.2 and I have to accept that we are infertile. We are not going to have a baby.

I am sick of the sad looks and pity from others when they ask the dreaded question and I say... we have been trying and can't pregnant.

I am sick of the guilt I feel for failing to provide a sibling to my poor existing child who has had to put up with my TTC obsession.

I am sick of the amount of money and time I'm sinking into this even though I know my efforts are futile.

I am sick of people saying I should be grateful because I have one.

I am sick of the ignorance surrounding secondary infertility.

Fuck this shit basically.
