Hi Franz,
It's good to hear from you.

Sorry you are having a challenging time.
Is your wife around and able to lend some support?
I know you travel a lot. Are you near your pdoc?
I am very concerned as you tend to spiral very quickly. Have you been in touch with your pdoc? Does your pdoc tend to adjust your meds when you get depressed?
I hope the depression does not get any worse. I am very concerned about you.
Keep reaching out.
