Coming from someone who totaled his 04' VFR and injuring his knee. I think you already passed the first hurdle by getting back on another bike. With seat time, you'll regain your confidence and be back to your old self.
For me, as soon as I can walk I went out and got another bike. I knew the longer I waited the less likely I'll get on another bike again. Thanks to a great group of friends that I ride with, I slowly worked my way back. Just take your time and hopefully things will return to normal.
