Alt burnout

It is going to be my fourth year living and teaching in Japan. But I am an alt and I am a t2 teacher. I often feel underutilized and bored out of my mind. The students make it so much more worth it. I am also tired of feeling like I'm a nuisance from the staff. 🥹 We (alts) are in a separate room than the staff room and we miss most meetings and miss occasionally important information. I have told them like if it's something important let us know or we can sit in the meeting. I have tried to pitch English ideas such as English day , team teaching or englsih game day during lunch break but still feels like no matter what ideas I put out or how much I say it nothing changes. I feel like I keep trying in hopes to make a better work environment for myself, but it really doesn't feel like much has changed. I'm also feeling tired of feeling the need to advocate for myself. I've been feeling a lot of resentment towards my school. How do you think I should try to fix the resentment and burnout?? Or this a sign it's time to change jobs?
