Sorry this is messing with your enjoyment. I just want you to have fun. Skateboarding shouldn't feel like a chore you need to do.
Whenever I get anxious about skating, I take it back to the basics. Just ride and feel the sensation of the board under your feet. Do simple grinds and slides and enjoy the tactile vibrations on your feet through your shoes.
The stuff that comes easy today will be difficult years from now. Push yourself, but don't knock yourself down.
