I'm having the same problem on my skateboard. I've been skating for 4 months now. I'm right-handed and my dominant leg is definitely the right one. Still, I started skating goofy because at first everyone told me I shouldn't care about my dominant hand or leg but I should just go with what felt more comfortable. I guess balancing on my front (right) leg felt way more comfortable, so I chose goofy, but in the long run it was a disaster. I can't ollie nor manual properly because, really, most tricks need your dominant (or at least a strong) leg in the back.
But there's more.
I tried a carver skate (the one surfers use to emulate surf moves. it's so damn fun, you should try it) and no matter how hard I tried, I couldn't pump goofy. So I tried the regular stance and managed to pump almost instantly. At the moment, I ride my carver skate regular and my "classic" skate goofy. Also, this winter I tried snowboarding and it felt more comfortable riding regular.
Sooo I guess I was a moron because I've always been regular!
I've decided to change my stance and I'm practicing riding regular on my skateboard too. It's initially frustrating because you gotta re-learn all the things you can already do with the other stance but it still feels like the right thing to do (and I feel like I'm improving faster than I improved when I started skating goofy, but maybe it's because I'm already -more- confident on my board). I've thought about quitting in general. Still, every time I decide to "give up" and come back to my goofy stance, I can see that something's not right and I'll probably never be able to ollie properly because I'm missing that speed in the execution, I sense a surprising lack of strength in my left leg (consider I've ALWAYS practiced sport since I was a child, so it's not like I don't have muscles). Also, I know people will say that everyone can learn tricks switch so why shouldn't I keep skating goofy...etc... but I can only skate like 3 times a week, 1h at best each time, so I really don't have enough time to train my left leg to do the hard work (obviously, not on my skateboard).
I wish I could be more helpful and say stuff like "I've changed my stance AND it resulted in..." but I guess I'll have to wait a couple of months of practice before knowing if it was worth it.
I suggest you don't lie to yourself and do what you think is right. Maybe it's the annoying thing to do at first, but I'm confident it will reward you in the long run.
(also, if you learn at least to stand on your board with both stances, if you ever decide to go back to your initial stance, you'll be more comfortable riding out of a trick switch

)(oh and you're young, don't listen to anyone. I feel like I'm super old, starting skating at 21 and yeah, maybe I'll never land a treflip, but who cares when you have fun)
