Hi everyone. I wanted to share my experience and see if anyone else has had similar and what might help?

I’ve managed depression anxiety for 20 years, but this year I’ve experienced the worst time ever - with extreme diurnal mood variation. I wake up feeling simply dreadful, tearful and anxious and then as the day passes it improves. By the evening I start to feel better and confident about the next day - only for the cycle to compete. I’ve been off work for over 9 months with 3 unsuccessful attempts at returning. I’ve had medications switched, a recent experience of seratonin syndrome, and I’m at a loss of what might help. My psychiatrist suggested augmentation with quitiepine but I’m not convinced. I wondered what experience any of you might have had with depression Nd extreme anxiety on mornings and what helps? Thanks so much for reading
