I had similar symptoms. Started tapering from 150 down to 75. I was fine for two months, just a little sensitivity like you. Then decided to taper to 37.5. 3 days later I was in hell. Constant severe anxiety, depression spells, couldn't eat, sleep, work, or distract myself with anything. The physical and mental symptoms were unbearable. After a couple of days my doctor upped me back to 75mg and I had hope again but it wasn't better at all. Maybe even worse.
I gave up hope and thought I would have to hospitalize myself or I would do something to myself.
But then my doctor upped me back to my usual 150mg and gave me 1mg of clonazepam a day. Two days later I felt free. I was back to my happy self, I could work, my appetite came back and I was sleeping through the night.
My point is, maybe if you go back to 150 mg you'll feel okay again.
There is hope. I wish you strength and patience, we all need it in this process.
