I feel like I’m at an intermediate stalemate

Edit: Thank you all who answered so far, unfortunately I don’t have any videos from my last trip. I’ll be sure to ask a friend next time so I can post it here if I keep having this issue. This is the first time I’ve heard of the term backseat, so I’ll definitely keep it in mind, maybe even take another lesson to really make sure. A few years ago, skiing was the one thing that helped me cope with things going on in life. I’m not good, but learning something like this made me feel really good about myself. I’m just fearful of backtracking in progress so I think a lesson will be worth it, getting some videos, etc.

Hi and happy new year everyone! I started to learn how to ski about three years ago. Last year, I remember feeling a pretty big improvement and I was finally able to keep up with my friends. I would fall here and there, but I could keep up and finish runs without breaks, I really enjoyed it. I felt pain in my legs during skiing but I thought the pain that comes with carving turns in your quads and calves would eventually go away.

Fast forward to this year, I just went on a skiing trip and I feel like I’m at a stalemate. I don’t know why I’m scared to go as fast as I used to last year. Secondly, the pain in my legs while skiing is just not enjoyable and I just need to constantly take a break on a run. I don’t pizza the whole way down, I work on keeping my skis parallel. To be more specific, halfway down a run, I just find myself regretting even going on the lift in the first place, and my legs just HURT. I’m not out of shape or anything, but I don’t understand how others can just keep going down the whole run without needing to take a break, even if they haven’t been for a whole year. I also just notice myself going slower because of this pain, and being scared. I really fell in love with skiing but this last trip, I just didn’t enjoy myself at all and I’m extremely down about it. I feel like I may be doing something wrong and perhaps I should get another lesson. I don’t know if it’s normal to feel like this because all of my other friends are snowboarders and I didn’t know where else to turn. Thank you in advance and again happy new year everyone!
