Don't be too hard on yourself there, Ive been driving a manual for 2 months now which is how long Ive had my subbie. I thought Id never learn how to drive one and was kinda scared too. Luckily for me I had a friend that had a jeep which had a manual transmission. We went to a parkin lot and drove for an hour and showed me the techniques of shifting. The best advice I can give you is for you to find a buddy with a manual and go find a parking lot. Once you learn you'll never wanna get outta the car! Best of luck!
I love my Subbie!
