TTC hope?

Hi all, me (32) and my partner (33) have been ttc for 8 months and we have had no luck. My periods are regular and I ovulate, both of us have no health issues, ive never been pregnant or had a scare. Going completely mad, feeling heartbroken. Completely underestimated how savage and lonely TTC would be! Two of my best friends got pregnant after 1-3 months of trying and are now happily on their way, both of which weren't even that bothered about it a few years ago. I've always wanted to be a mum, it's the only thing I've ever been sure about. I can't stop thinking about it not happening, it's so hard to go through every month of more disappointment. I know this is strange but hopefully someone will understand, I find myself even wishing for a miscarriage just so I know we are capable and that there is hope to conceive again. Is my time running out? I thought I would be on my way by now and I don't want to be an old mum. Not really sure what the point of this post was other than to hope that someone sees it and comments a positive story? Xxxx
