I am so sorry the people who assaulted you did not get caught. That has got to be frustrating.
I understand how you feel, depression-wise. I don't live in Vegas, but I am used to being out and about activity-wise (Exercising, training, etc) and doing active things with the kids. It IS hard sometimes. ( I am 7 months into this now)
And I know it is hard to keep hearing that you really have to try to think positively, but that is the only thing keeping me going right now, and I am not going to lie, it doesn't work a lot of the times.
Keep hanging in there, and I am not a doctor, but maybe the damage caused by the teeth will take a while to heal itself; it took a while for it to impair you, so maybe it will be a little while to detox from your system. Just a thought?
I know this probably didn't help a lot, but I am thinking of you and hoping that things start getting better for you.
