Hi Karen,
I teach Photoshop classes locally and I will admit that the first time my students start in it they usually feel a bit overwhelmed but if you have a good teacher that understands the magnitude of the program he/she will answer your questions and help you work through the "wow" of it all.
It can be a great program and if you can have training on it that will make you sucessful quicker than going at it on your own.
As Julie Ann has said though, if you don't plan to do a lot of designing, etc you may LIKE elements better

if you don't have either I'd recommend downloading both and trying them out.
If you have questions feel free to ask!

HTH!
