I always ask myself these questions before saying yes to anything:
Who is this person to me?
Is the request something I want to do?
Is the request doable and within reason?
Will the request be stressful or require a lot of time?
Am I being paid and if so is the amount beyond sufficient for my time, efforts and any frustration?
I hope your recovery is going well, and remember, no is an answer and you don’t have to explain or justify your answer to anyone should you choose to say no.
