Kev,
Sorry you've had such a difficult time.
The others beat me to it - fly dual for a bit first. The spring and summer are ahead so hopefully you'll have plenty of time to get back into to gradually as you feel ready. Plan some trips with friends and enjoy it.... that's what it's all about. Then when you're feeling more ready plan a short solo trip to start and build it up.
I had a crappy time last summer and hadn't flown solo for a while, quite a bit of P1 with someone very experienced in the RHS (who granted, was not flying it but I was still aware he was sat there) but very little by myself. I flew by myself for the first time in a while in sept and was very aware that my capacity to deal with anything untoward was reduced but after a few sensibly timed trips, things were much better.
Good luck and let us know how you get on
B
