Need some advice

Ok I need some help...

i am in the practical nursing program in ontario which is 2 yrs in length.. i am in my 2nd semester of first year... i am loving every minute of it and would like to be an RN (i wasn't 100% before so thats y i chose rpn cuz rn is 4 yrs)...

since i know i want to continue would it be stupid to apply for the 4 yr RN course this september and drop out of the RPN program.. or finish the RPN program and then do the transitional program to RN which would be another 3 yrs after im done next year...

i am conflicted and worried about the amt of loans i have etc... and even though im only 26 for some reason i feel like im running out of time..

so any advice or am i just losing my mind...
