Yep, I know exactly how you feel - I'm in the same situation. I've been waiting to do a solo landaway since mid December. As well as the rubbish weather we have been having I'm also being affected by the surge in recruitment by the airlines - decimating the instructor population at the club where I fly. Whilst I'm really pleased for them getting the jobs they have waited for for so long, it means that I've had a new instructor for each of my past 4 lessons. So each lesson has been spent with the instructor getting to know my level of ability and me getting used to them.
I've given up now until after Easter, when I hope not only the weather will be better but I might be able to have the same instructor for consecutive lessons. Thats assuming that there may be new instructors available!
Its a frustrating sport sometimes isn't it!
