Opinions of Effexer for PTSD day time anxiety?

39 f here, so the last couple months my PTSD, and anxiety have been off the charts. I have had this managed for years without meds, besides using medical cannabis for night time use only. My issue is I struggle during the day now with triggers and very high anxiety, like the worst anxiety of my life. I made a appointment with a gynocologist (because I think this is me being perimenopausal as well) my medical cannabis doctor suggest I make a appointment with a psychiatrist, and ask about effexer, so here I am, wondering if effexer good for PTSD anxiety, intuitive thoughts caused by triggers, and etc? My appointment with my psychiatrist is January 7th. I also start trauma therapy as well.
