I don't want to share photoshop that I paid for
Why not share your photoshop?
Because I can share other stuff for free except PS
It's understandable that you don't want to share something that you paid money for. If you did it would probably be difficult to share with others. How did you get it?
I bought it from my college lab account.
That's great you paid for the proper license for school. I wish you the best in your studies!
