TTC so long you're over it?

Has this happened to anyone?

We've been TTC for years, have spent a fair amount of money on investigations, and still no answer. The doctor wants to do more invasive (IE expensive) investigations and honestly... I'm over it.

I do want a child, but the effort has really put me off. Every step is a mountain and it hasn't been easy to even get to where we are now. So many stuff ups along the way, I'm starting to wonder if it's not a sign.

I've been thinking of giving away all the baby stuff we bought in anticipation and calling it a day on this.

It breaks my heart, but I'm so emotionally drained I don't even want to have sex anymore. These last two months I have completely avoided sex during my fertile week because I know it will amount to nothing and I'd rather not spend a TTW thinking "maybe this month....".

Anyone else in the same boat?
