Anxiety with moderate jaw pain.

I have anxiety and panic disorder from one year and history of depression and social anxiety . Used two antidepressants with clonazepam since 2020 .  Three weeks ago I stopped the nexito because of epigastric pain(may be ulcer) and non improvement of my depressed mood with anxiety . After stopping nexito my psychiatrist prescribed Venice xr that i haven't eaten yet . During the use of nexito i have teeth pain that is not noticeable but when stopped it aggravated now pressure on jaw radiated to teeth managed with paracetamol . My ecg is normal and also blood pressure 110/80 . Currently i have low mood due to recurrent anxiety attacks that managed with clonazepam . Is this pain due to nexito withdrawal or caused by nexito usage or anxiety In this situation can I Start Venice xr or need to address and  take separate treatment for jaw teeth pressure before starting the medicine ?
