what on earth is your gynaecologist thinking! That's why a dedicated menopause clinic is a better way of getting appropriate treatment for peri/menopause symptoms.
How old R U and what are you periods up to? Anxiety can increase as hormones rise and fall. How long had you been taking Sertraline, the jaw clenching may well have been anxiety.
I have been on several types of AD since 1989. Once I found 1 that didn't cause nausea my depression improved, I have different medication to ease anxiety. All ADs helped for several years and I take escitalopram 5mg morning, 10mg at night, without problems. Which does has been prescribed and which side effects would be intolerable for you?
Your mind is, like mine used to, whizzing. DH asked me what my worries were but there was so much so fast in my brain that I couldn't tie anything down! Anxiety feeds anxiety sadly

. mayB try Citalopram on alternate nights or every 3rd initially and see how you feel. What's the worst that could happen?
Anxiety is never logical so your lack of resolution etc. are 'within normal limits' when highly anxious. This will pass!
Do U have a nighttime routine? My bath is my haven, cuppa and good book or magazine. When severely depressed I was unable to stay in the water for more than a few moments, nor could I concentrate on much at all. As the medication kicked in all that improved.
........ and breath. Not easy. Do U live alone etc.?
