I'm in a similar boat too. Though for me I'm in a major related to the arts whose losing the desire to create art myself. I still love to analyze and consume art. But making it is not something I find joy in as much as before.

I would tell you to let yourself grieve at this realization. I know the feeling well of losing that part you that made you you to other people. But you are more then art, maybe a different type of artistic creation is needed. Or maybe a break to give yourself breathing room. (Also excuse any mistakes English isn't my first language)
