Hello and welcome to HealingWell. I sense you are frustrated and having difficulty dealing with the people on your team as they are not as quick as you would like them to be. I am not sure re medications so I will leave that to your Drs.
I was a manager of a very busy Emergency Department so I understand your frustrations.
When you are struggling with a deadline or dealing with delicate decisions, the last thing you want to deal with is "people". When the fight is really on and the battle is undecided, you want your team to act co-operatively, quickly, rationally; you do not want a disgruntled employee whining about life, you do not want a worker who avoids work, you do not want your key engineer being tired all day because the baby cries all night. But this is what happens, and as a manager you have to deal with it. Few "people problems" can be solved quickly, some are totally beyond your control and can only be contained; but you do have influence over many factors which affect your people and so it is your responsibility to ensure that your influence is a positive one.
You can only underestimate the impact which you personally have upon the habits and effectiveness of your group. As the leader of a team, you have the authority to sanction, encourage or restrict most aspects of their working day, and this places you in a position of power - and responsibility. It takes great patience to deal with the frustration of trying to meet deadlines when you staff is not giving you what you want from them. This is the human factor you must deal with as the Project Manager.
Wondering if you have ever tried meditation or been to a therapist to help you learn ways to slow down your thoughts as this may be the way to go. You cannot change other people, you can only change yourself.
