Please help (stalking situation repost)

I think I’m being stalked?? It started about two months ago when I noticed a guy trailing behind me on campus. I didn’t think much of it, it’s a super tiny school and he probably has classes around the same area, but when I started taking different routes he’d show up trailing behind again. Everywhere I turned he just happened to be there. He’d follow me to the library, sit a few chairs down, then leave when I’d leave to follow me to my next class, or he’d linger around my locker. One day he walked past my work and I recognized him as the same guy from school. He came in and browsed around, again I didn’t think much of it. He continued following me around campus which is normal, but he began visiting my work nearly everyday. He’d only stop in for a few minutes but it was strange because I work at hallmark!! What could he possibly need at hallmark so much?? A snow globe?? A greeting card?? It started to creep out my manager and coworkers. On my lunch break he went from passing by me in the mall cafeteria to sitting a few tables across from me watching me. This is were I’m genuinely afraid and need help, but about two weeks ago when I was getting out of work he followed me to my car, and as I pulled out and drove off I noticed he was following me home. I didn’t go directly home and I just drove around for a long time, eventually he stopped. A few days ago i found he followed me, my ex boyfriend, my current boyfriend, my mom and my little sister on social media. He’s taken MANY screenshots of some of my stories so I haven’t posted anymore. It’s been pretty harmless and honestly he looks really unthreatening and normal, but it’s scary having someone constantly following and watching you from a distance. I don’t know what to do, and I defo don’t want the situation to escalate. This is a repost due to needing a bit more through advice, thank you!!
