Dear Scott,
I am not an english speaker, so I will just keep it short.
If I were you I would not take the role, I would take the decision, stick to it and accept it. Instead, I would take some time off to relax and if possible, deal with my depression and self confidence.
I don’t want to feel guilty and stressed all the time, so I have to do something that gives me joy and happiness, perhaps a change in lifestyle with at least 1 hour of exercise everyday.
Be happy and live strong mate!
