PS CS5 vs PS CC

[Neverland Scraps]

Piggy-backing off my previous post about losing all of my styles---deep breath, it isn't the end of the world........

I got a free year subscription to Photoshop CC through my photography class (see that's positive! ). I didn't want to go over to Photoshop CC until I was confident with my shadow styles. Since I lost everything, should I just take the leap and uninstall Photoshop CS5 and move forward with Photoshop CC?

Or is it a major learning curve going from an older Photoshop (I only missed Photoshop 6 before CC came out) to Photoshop CC?

I think I need someone to give me a hug (I need one--maybe a couple--today) and hold my hand

Who is using Photoshop CC?

**********THIS IS AN OLD QUESTION
Someone recently (in December) bumped this post. I have decided to continue using my Photoshop CS5 and not upgrade to CC because I cannot justify paying to rent a program when I already own the program.
