Dear Alexander:

I wonder if it might be a good idea for you to talk to your employer, the one paying your coworker’s salary, about your suspicions that he may be costing the company financial loss, maybe loss of reputation with clients, because of his irresponsible behaviors (?)

As far as the enormous stress, anger and sleepless nights that you are experiencing because of your co-worker: you are experiencing this distress because you are thinking about him, thinking about him a lot, am I correct?

If I am correct, then you need to greatly limit the amount of time you spend thinking about him, especially after work and before bed time. When you find yourself thinking about him, getting caught in the thoughts (and in the distress that accompanies these thoughts), think to yourself: is there anything I can do about any of this? If there is, make a note of it and do it when the time is right, then stop thinking about it. Think about him only if there is a practical reason to think about him.

We can discuss the topic further if you want, after you respond to this post, if you do.
