Giving it a little more thought you need some help finding a reasonably priced reliable but good camera.
At your age I had no encouragement from my parents at alland no-one for advice, I ended up buying aRussian Zenit E after saving my pocket money. I wore it out in 2 years but it did its job and got me hooked and I had some newspaper front pages and magazine cover shots while at school.
I've always shot film, I've also used digital for many years, I still prefer film when practical but then I'm pre-dominantly a Large Format photographer, a wood and brass field camera 5x4 film.
What I'm getting to is shooting film means think a little more before pressing the shutter, is the exposure correct, what about the subject matter and composition ? After a short while you have total confidence in you equipment, technique, and ways of working. It's a discipline that gets lost with many people who have only used Digital capture. It's not remotely difficult though, two excellent books are Curt Jacobson, Developing 18th Ed it's cheap second hand and Enlarging of a similar era.
If you want to start enlarging I have a free enlarger here in theUK (for UK postage/shipping only) on another Forum, I was given it to see it went for good use. It's not the first I've given away for free

but others do the same across the world.
Just keep your parents fully informed of your wheeler dealings, see if there's anyone local in the Ilford Local Darkroom scheme, I've helped a few others through this including a very severely disabled photographer - i was the only darkroom with disabled access only because no stairs
I was lucky at your age while little to no pocket money but I'd shoot macro work etc for other biology students and that helped pay for my film and paper. These days I'm definitely old enough to be your grand father but money's tight so choice of film can be important. For critical and project work I use Ilford Delta100, 200 and HP5, for non project work I shoot Fomapan 100 & 200 35mmre/120 and 5x4. 7x5 & soon 10x8, however I'd be OK using these films for all my work if I had too. Even cheaper a Freestyle EDU films, these are jsut rebadges Fomapan.
When I was you age I bought a lot of ex-Government/Military Ilford FP3 and HP3, I'd guess the difference between FP3 and FP4 was more significant than the differences in terms on final image quality compared to Fomapan 100 & 200 and FP4+.
