I really, really wish I could give you a real hug right now, but this will have to do:
*gives long, comforting, reassuring e-hug*
I'm so sorry for all the painóboth physical and emotionalóyou had to go through.

Honestly, if your stepfather really thinks that missing a day of work is worth more than you not suffering in agony (not sure if I wrote that right, but you know what I mean), then…well, at best he's got some seriously disorganized priorities, and at worst he's being downright cruel.

You certainly shouldn't feel like this is your fault, Sparky: no one could have predicted that the anesthetic wouldn't work for you, or what your pain tolerance would be in this scenario. There are plenty of people out there who (no offense to them) would probably be unable to sit through such a procedure because they'd have no control over their body's fear response (i.e., they'd be shaking too much for the dentist to even get started), and others who would be too nervous to get in the dentist's chair in the first place. (Heck, situations like the one you experienced are exactly the kind of reason so many people are afraid to visit the dentist!) You did your best to see this thing through, but as you said, your body just couldn't handle it. That's nothing to be ashamed of.
I hope you get that tooth taken care of soon with no further complications, and that you feel better in all respects. As always, you're more than welcome to PM or e-mail me if you need to vent, if you need a confidant, or if you just need emotional support. I promise you I won't mind. *hugs again*
Your buddy,
Pangy
