I forgot to mention, my last day of altar serving was last Sunday. I was glad it was over, it really hit me that that was the last time, but I was happy to just be able to relax and take in the Mass in future. It was a bit of a disaster, we lost our priest a couple of minutes before Mass and we made a few other mistakes, and so I'm definitely not tempted to go back.
The priest in charge of training servers was very supportive too. I'm glad it ended so well. I'll continue to pray for the servers too, that this becomes a vocation for them
