Hi Marmoset,
Welcome to the forum! How do like your life as an ALT? I used to be an ALT myself and enjoyed it a lot especially in the beginning of my second year when I already knew the routines etc. The third year wasn't that fun anymore because I just got annoyed by getting used to a new school and the school to me, being used to it I already had to finish it and had to go to another school to do the whole process over and over again (I think I have been to over 30 schools here in Kobe within 3 years. )
Maybe time to find some other friends whom you can speak Japanese with?
