The root cause of the problem is still there and cannot realistically go away easily [1]. I'm consulting with psychologists and was taking medicine (held currently by the lock down). It has not helped to read literature myself [2] as it only says sadness and depression are likely given the circumstances.

Among the good things: I have a good job [3], have several friends who are supportive, am trying hobbies like music. I'm generally exercising also, slowed by lock down.

[1] I've been in an abusive and sexless marriage for over a decade, living separately now. Spouse has filed a false violence case against me, the matter is in the courts and proceeding at its own pace. And there's more.

[2] E.g., Maslow's hierarchy of needs (https://en.wikipedia.org/wiki/Maslow%27s_hierarchy_of_needs)

[3] My performance is below my standards due to low motivation and negative impact of stress on memory. I am barely able to do anything myself, however, I'm doing great in guiding and mentoring others which is an important part of my role. It has helped to let them know of my personal situation and everybody is supportive.
