I feel my family doesn't understand what I go though with anxiety and depression and are quick to ignore me or criticize me for my actions. For me, I look for help outside of my family: therapists, an acupuncturist, this site, online friends, and one former coworker that I know that struggles with anxiety.
I wonder if the TMD and physical issues are heightening your anxiety. Either massage, yoga, and acupuncture might help. I believe the physical wellbeing has a huge influence on our mental wellbeing.
I can relate to that feeling of losing friendships. You have so much to give and hurts when a friend rejects that.

I hope things get much better for you.
