Thanks everyone for your comments. Your support is very much appreciated.
I'd like to add - especially for anyone out there still learning - that I didn't think last weekend's flight would happen. Leading up to it I was questioning why I was learning to fly, and whether I had it in me to be "pilot in command" after relying on my husband for so long. All the week before I was battling with myself - every bone in my body was not wanting to go for another lesson, but my heart knew I would be disappointed if I didn't. Everyone I spoke to said everyone goes through this, so I forced myself to book in for my lesson.
And it was the best thing I could have done. Flying solo is the most exhilarating thing I have ever done - and I've done a lot of thrilling things - and now I know why I am taking flying lessons. So I can get up there on my own, away from it all, fully in control, and hopefully land safely back on the ground.
So I just wanted to share this with anyone struggling with their training. Ignore the doubts and the fears and just do it. Otherwise you might miss the best experience of your life!
