Hi anonymous6969!
I can only imagine that this weekend will be dragging on for you, and that Monday feels like a big, looming, horrible doom...
I think you are amazingly brave and courageous for getting yourself to the dentist despite all your fears, and also for posting and uploading a picture here. Before I started fixing my teeth up, I would never have been that brave! So, :bravo: for being a wonderful strong person.
I looked at your picture and honestly don't think your teeth look that bad either. Like many people here, my teeth were cracked and broken, many down to the gumline, with big jagged bits and chunks of metal and... well, just hideous looking things. I expected my dentist to completely freak out. But she didn't even flinch. I'm about halfway through a big treatment plan, but only two of my teeth needed extraction (and these were worn/broken below the gumline, so they kind of weren't there anyway). The rest are gradually being rebuilt and look better than ever.
There's no way to tell from just looking-- even a dentist needs to see x-rays to understand what's really going on-- but I really think that you're FAR from being a "lost cause". There might be a lot of work to be done, but I'd be that most or all of your teeth can be saved and restored. Try not to get overwhelmed by how much or how long-- for now, Monday's appointment is just about getting some x-rays and letting the dentist take a look, and then discussing what needs done. No poking, no drilling.
Good luck getting through the weekend, and feel free to post here if you need some additional help and encouragement. I'm certain you'll be back here Monday night posting "It went really well!!!"
Great job again getting this far-- you're almost through the hardest part, and then it's all smooth sailing!
