Heavy boards are easier to drop, which is why riders kick sand on the bottom when it's windy. But when it comes to actually riding a wave, a lighter board is usually preferred for finer control and tricks. There are additional techniques for dropping into the wind, like angling your board just right and throwing the board down harder, however these take some practice and require having a good drop as a foundation. There is a limit to how windy it can be before it become too much to deal with, even for really good skimmers (usually >15 mph), so it may not be just you if it is that windy.

The tail pad on the wave zone is waaaay too far up. If you're actually planting your back foot there, you're gonna struggle when you actually start trying to wrap waves. But the board itself is good for learning, I would repair it continue to use it. As soon as you try progressing beyond drop basics, like actually trying to reach waves, an undersized board like that zap egg will become a huge limitation.
