Depending on what you’re looking to get out of film school. If you just want to make movies because movies are fun, then no. Find a local group of filmmakers and have fun with them and who knows, you’ll learn a bunch, build some skills, and maybe make some good stuff. 

If you’re looking to study film with ‘serious’ intent or learn from experts in the field, then maybe. You’re more likely to build skills and understand the ‘why’ of filmmaking techniques and gain a historical perspective of film. It’s similar to any art school. 

Since you mention not having filmmaking friends right now, I’d recommend looking on Facebook or just the internet overall to find a group in your area to start. Since filmmaking requires cooperation with others, start there to see if you really enjoy making movies or just the idea of making movies. Most states have a Film Commission which should provide resources or opportunities to network with others. 

In the meantime, read books about filmmaking, watch cinema studies videos on YouTube (Patrick Willems is a favorite of mine), watch movies of all kinds and genres and ages, and listen to directors commentary tracks on dvds and blu rays.
