I’m feeling a bit at the end of my rope here. I was recently diagnosed with an autoimmune disorder in addition to the GAD. I agreed to try meds for anxiety but it’s been tough going. 
Buspar gave me insomnia, 5mg Prozac gave me awful teeth clenching immediately, Vistaril does nothing, and I don’t want to take benzodiazepines for many reasons. I’ve been scouring the web and people are saying tricyclic antidepressants but they come with a lot of side effects…?? 
Does anyone have any luck with an SSRI that doesn’t increase teeth clenching?
I’m a mental health counselor so I do all the anti anxiety coping skills but it doesn’t really help. 
Honestly, my anxiety was uncomfortable but tolerable until I was diagnosed with the autoimmune disorder. I’ve been a wreck since then.
