seriously just don't give up park, my first season (well the previous one) was so shitty, at the end i was barely able to clear a flat rail or stomp a 180 over a 20'jump. I've been skiing 3 times so far this season and i can do 3's and 180's and 270's out and stuff like that. so don't give up, you'll get better, even if it takes some time.
