Learning on a 5 string

I'm a beginner bass player right now, and as the title suggests, I'm learning on a 5 string bass. It's the only bass I have access to cuz my mom gifted it to me without knowing basses usually have have 4 strings, but I find myself never really needing to use the low b and I feel like I'm unworthy of having one if that makes sense?? I dunno
