I am intrigued by the concept of "Mental Health Gym" by James Routledge.
At work people can be magic if you are honest with them. This book is an optimistic outlook to mental health at work.
I do believe that, deep down, most of us are capable of empathy. Some of us might have to work hard at it, but we are all able to identify with others amidst work situations. In being transparent about our problems at work, it is to important remember that, while most people do want to help, listen and understand, they may be reliant on you actually asking them to. Not everyone is perceptive enough to pick up on when you are feeling bad, but it doesn’t mean they don’t care. The world doesn’t stop turning when you are open about your mental health nor should it.
Realizing that people usually just want to get on with their lives with you in it, in whatever capacity you can manage, is important. If you need to be listened to for a while, you might have to say so. Reach out. Reach to your team, your sub-ordinated, your managers.
