About 3 months ago, our teams restructured and I was offered the opportunity to be Scrum Master for the new team. The role pretty much meant 1) being in charge of scheduling the necessary ceremonies, 2) being default facilitator for the meetings, and 3) making sure the team upholds the promises they said they would do. There is no authority in the additional role. Wanting to improve my leadership skills, I took the role.
For some context, I have been in previous teams that have had a Scrum Master, so I saw what tasks they did, but I myself have not been one yet.
Since the 3 months of being Scrum Master, I have found the role to be a lot more stressful than I thought. I struggle a lot with the facilitating meeting aspect of it, and with making sure the team does what they say they do. I was given a Scrum Master book from my previous team lead, which gave practical tips and example scenarios, which I found very helpful, but it also shows the Scrum Masters being able to ask relevant and revealing questions on the spot, and impromptu speaking is not something I am good at. This also explains a bit why facilitation is difficult for me - you can't plan ahead what people will say, and you don't have time to decide what the useful questions for the team are.
On the other hand, I want to be able to facilitate groups, and develop my skills, and grow as a person. I realize this position is going outside of my comfort zone, but I am not sure if it is too much out of my comfort zone and leading to burnout.
I had a year-end review with my manager last week, and he noticed that I was stressed out and frustrated with the Scrum Master role. Other team members have picked up on this as well. He... suggested that if the extra role was too stressful for me, then maybe it would be better if someone else had the role, someone who has an easier time with doing the things I struggle with.
This brings me to the main question: Should I continue an extra role, if it is highly stressful for me, but it is an area I want to improve in?
Should I continue to get better, or stop because it isn't a good fit?
