I use Photoshop rather than Elements, but a lot of the basics are exactly the same. The first time I installed it I just couldn't get my head round it, so promptly uninstalled it. When I finally got round to loading it back onto the PC, I took the time to go through various tutorials that can be found on Youtube and similar, and haven't looked back since.
If you can learn how to use layers and masks, that should give you a good grounding to build on.
