It's good to play people that are better than you. They will punish you for the mistakes you make and you can learn and improve. But if the difference is too big it's not fun at all.
It would be a lot more enjoyable if you can find tournaments on your level. Keep grinding and following lessons and play as many different opponents as possible, every opponent plays different and you have to adapt and figure out their weak points, or focus on your own strong points. Tournaments are great for this. Also if you have nerves, they will get less with every tournament you play.
What will also help is to train one on one, you can play cross court or straight and work on your consistency. Play one ball low, one high, and repeat. One at net and one at the back and practice hitting before and after glass. that way you will learn fast!
I'm at a decent level now after playing for 4+ years, but in every level there will always be better players than you. Just focus on your own improvement!
There is a lot to learn in padel, make sure to enjoy the journey!
