At 18 I'm by no means a nostalgic old man revisiting simpler days... but I'm using my 7D less and less, and using my Canon AV-1 more and more (very similar to your AE-1)
I find the whole experience more enjoyable and more gratifying, and I like the look of film much more. I'm coming very close to actually just selling my 7D and lenses and shooting exclusively on film. The video is the only thing stopping me right now.
I'm not a purist wannabe snob, digital has Its place and for many its the superior tool... but I just don't get the same pleasure shooting with my 7D, so it feels like a lot of money not being loved. I hoped I'd get the same satisfaction from a full-frame DSLR, but after using a 5D Mark2 I still wasn't loving it.
I tip my hat at you, but don't sell your 7D.
Shooting film is an entire different ball game. It slows you down and you think about every shot carefully.
I started in SLR photography in the 1970s, processed my own B/W and it's a very satisfying thing.
I've been toying with the idea of going back to 4x5 B/W photography just for the heck of it.
