Welcome to the forum! You will LOVE it. Everyone is so helpful.
I don't think you are doing anything wrong. Just keep at it. It takes a while to get the tension right when trying a new technique. I tried continental style, but I still prefer knitting English style. It's just easier for me and I'm happy with my speed.
Just don't give up. Practice, practice, practice! The more you do, the better and easier it will get.
Good luck and welcome! I hope this helps.
