Sounds like a good opportunity to learn to shoot from the off shoulder.
A small square of scotch tape over the 'off eye' (your old shooting eye now) where it tries to look at the sights will help the transition.
Learning now will help later on in life as the shoulder starts to cause old injury problems for you.
Same thing for handguns. Learn now to shoot with the off hand. The heavy calibers transfer some of the recoil to the shoulder.
