I am sorry for that Jess.
Just recognise that Aikido is constant change. If you hate changes, probably the Kami made your sensei move to teach you a lesson. Accept it and move on to new chances and new adventures.
Hopefully they are related to Aikido
P.S. There is no need to see it esoterically. But the fact is out there and now it is your turn to make the step forward.
