Feeling Very Stuck

I do not have very many skills or interests (that I know of) but I'm willing to quit my current job to pursuit anything I'd be passionate about. The big problem is that I don't know myself or know what I want. I'm currently in Purchasing for a community developer but I'm not learning a whole lot. And I'm scared this would be the case with most other jobs.

This is my first long term job (I'm 23), but I'm almost a year in and its just not clicking. My boss has indicated that I'm not performing well, because I'm inefficient and should be doing more for the department at this point. Whatever, but the idea of leaving for something I'd understand better or be passionate about gets me fired up, but I just don't know what that is. I'd be willing to try anything from internships, to more school, a masters program, certifications, or starting another entry level position, etc. I just simply want to learn and grow especially while I'm young because right now I feel very stuck.

I can tell you 2 things that interest me: how the brain works and designing things. The other day I thought to myself how cool would it be to design cities. I used to want to be an architect when I was younger but never got into it. I doubt I have the creativity or brain power to do it. or maybe I do and I'm just doubting myself. I often think about mental health and how it would be cool to study the brain or like human behavior to help people better their lives.

Not asking anyone to hold my hand here but just some guidance would help because I'm insanely overwhelmed right now. Whether its regarding those two interests I mentioned or general advice on how find myself, please share your thoughts. There are endless possibilities or carrers in 2025, but to me it feels like there are none for me. Thanks for reading
