When I looked at the questions, I felt that there were more than one that I could have chosen...would it work to have your top 3 reasons? I ended up adding other for to me, the significant trigger was death of his mother.
I do understand that perhaps only choosing one gives the opportunity for better analysis of what we see.
I wonder what people who have been through a MLC would choose?
I understand that, but these polls don't let us have multiple options, as far as I can see.
Now, for this poll, we're focusing on depression and stress as key factors. I'd like to see if all MLCers have one, the other, or a category that is known as burnout. I don't think that's the same as being overwhelmed. Perhaps that's in the stresses/depressed category? It's also not the same as having a nervous breakdown (esgotamento in Portuguese, esgotamiento in Spanish), which is a psychological category of being unable to cope. (For lack of an alternative, perhaps these can be added to the stresses/depressed category).
Maslach burnout inventory, or MBI, is a specific tool to measure stress specifically as the result of work, and is recognized as a valid reason for taking sick leave in a number of countries. It's recognizes as a valid scale, with internal and external reliability. The MBI Surveys address three general scales:
1. Emotional exhaustion measures feelings of being emotionally overextended and exhausted by one's work
2. Depersonalization measures an unfeeling and impersonal response toward recipients of one's service, care treatment, or instruction. This includes "anhedonia", which is a loss of the ability to feel.
3. Personal accomplishment measures feelings of competence and successful achievement in one's work
Some writers propose 12 stages of burnout, some 4, some 3. In the following, note stages 6-11. Does it look familiar?
My H, an MD, diagnosed himself as high on the burnout scale, and I recognize many of these symptoms. However, at some point, rather than going into total collapse, when OW appeared, he seemed to go into escapist mode. He was contradictory and told me that (a) he could not feel anything, but (b) he was happy when he came home after meeting up with OW. He seemed to be fixed on his need to feel.
1. The Compulsion to Prove Oneself; demonstrating worth obsessively; tends to hit the best employees, those with enthusiasm who accept responsibility readily.
2. Working Harder; an inability to switch off.
3. Neglecting Their Needs; erratic sleeping, eating disrupted, lack of social interaction.
4. Displacement of Conflicts; problems are dismissed, we may feel threatened, panicky and jittery.
5. Revision of Values; values are skewed, friends and family dismissed, hobbies seen as irrelevant, work is only focus.
6. Denial of Emerging Problems; intolerance, perceiving collaborators as stupid, lazy, demanding, or undisciplined, social contacts harder; cynicism, aggression; problems are viewed as caused by time pressure and work, not because of life changes.
7. Withdrawal; social life small or non-existent, need to feel relief from stress, alcohol/drugs.
8. Odd Behavioural Changes; changes in behaviour obvious, friends and family concerned.
9. Depersonalization; seeing neither self nor others as valuable, and no longer perceive own needs.
10. Inner Emptiness; feeling empty inside and to overcome this, look for activity such as overeating, sex, alcohol, or drugs; activities are often exaggerated.
11. Depression; feeling lost and unsure, exhausted, future feels bleak and dark.
12. Burnout Syndrome; can include total mental and physical collapse; time for full medical attention.
Having said this, it has not been included in DSM-5, and has been criticized for focusing on work burnout, for being fragile in its construction, for being unsystematic in its approach and arbitrary in its categorization of factors, and for being similar to depression. See
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4459038/#!po=10.7143But I've included it here as its been mentioned by so many, including my own H.
However, the existence of stress and depression in themselves are not enough to explain what we see as MLC. As xzycf mentioned, there seem to be several factors together, or as OP has said elsewhere, a perfect storm.
I just want to see here if stress/depression/burnout are always present.
