Unsure about fire academy

I'm 2 weeks into the fire academy and I'm the only chick in it right now out of a group of like 16 guys. I don't know if I should continue with this, I joined it out of curiosity and cause I wanted to do more than EMT stuff. PT sucks but Im getting better little by little. I think the reason why I'm thinking about quitting is cause the idea of working with car wrecks and fires isn't that appealing to me and I'm afraid of not being strong enough, which I know with time, it'll fix itself. And even though I'm getting paid for this, starting to feel like it ain't worth it if I'm only gonna be a firefighter for a max of four years. I don't want a long-term career in firefighting. Just joined this cause I needed money, curiousity and wanted to better myself. All the other guys are excited but I feel like the odd fish cause I'm not excited for anything, just constantly dreading what the next day will bring. I'm just so unsure right now, I don't hate it but I don't love it. Should I just stick with it or put my time into something else?
