Caseload size?

I’m a 4th year bcba and I work in adult services. I know I’m kinda a black sheep in the field working with adults but I was curious about what yalls caseload sizes are? I am going on 17 I think and I am the only bcba in my company for the state I am in and I have no behavior techs. It’s just me and everyone needs everything done from scratch. I feel like it’s a huge load for me and I feel like I need to tell my boss that but I also don’t know if that’s a normal caseload size and I’m just being dramatic
