I was the same as you! I started back in May last year after not riding for 5/6 years after losing me confidence. I felt so sick I nearly cancelled it! I was glad I didn't.
My instructor was great and had me started on the lunge and assessed my riding and then the adjustments began! I'd never been taught on the lunge before and it really helped. I'm still sticking at it and can just courses around 2'3'' and have done some cross country jumping.
Good luck where is the lesson? Where abouts in sussex are you? I have 2 horses one is an irish cob full of life and the other a 2 year old warmblood. If near enough I may need a hand sometimes!!!
Just enjoy it, remember butterflys always make you perform better!! Wish i could have lessons in the day, work always get in the way....roll on light nights!!
I did book another one for a fortnights time. Can't do evey week as it's too expensive. Can't wait. They said I could go early and help to tack up and stuff, so that was really nice.
I even did some canter work, I thought I'd have been too scaredy but I was ok. I'm actually on the laptop...waiting for OH to get off the pc so I can upload my picture.
