That's the decision I had to make when I was 15 years old, when my mom absolutely would not allow a snake in the house, and I got a tortoise and a bearded dragon instead. Now I'm almost 19, living in college, and my mom finally let me have a baby snake (I'll have to move out before it gets too big, lol) if it means I'll be living at home this summer.
It took me 4 years to get her to budge, but in about three weeks I'll be getting my very first kingsnake/milksnake (not sure which).
My point is, I waited almost 4 years for the snake, and it paid off. In the meantime I just enjoyed raising my bearded dragon. Enjoy the reptiles that you have, and you'll get a snake eventually. And remember, the anticipation of getting a snake is really the best part. All this waiting will pay off in the end. Good luck!
Oh yeah, and if there are wild snakes in your area, I suggest that you pick up the hobby of field herping and photography. That's what I've been doing too. Since you can't keep a snake, you might as well go out there and find some! It's just as fun in my opinion.
