Why don't I like park skiing anymore?

For background, I've been skiing park for about 2 years now, and although my skills are laughable at best, I truly truly love it. I spend most of my waking hours during the summer daydreaming about it, watching edits and attempting to get my friends interested in it, (To no avail.) Going back to last winter, I was making good progression, and I was in a really good state of mind, but since this winter began, my mind just isn't in the right place, when I'm not skiing, I still think of nothing else other than freeskiing, and what new trick I could learn, but as soon as I click into my skis and look down at the park, I feel nothing but this gnawing dread and hopelessness. I try to force myself to progress, ease up and stop being so fucking scared for no reason, but if anything I just end up feeling worse, I actually feel relieved when the lifts shut for the day and I head home. I feel terrified to do tricks I've been able to do for ages like 3's and sliding a pipe. Right now I'm so fucking miserable because I'm simply not enjoying the sport that I love. I was just wondering if anybody else on NS might have gone through something similar, and if there's anything I can do to actually start enjoying myself in the park again. Cheers NS.
