Uninstall Photoshop and Creative Cloud

I installed the photoshop free trail yesterday and my iMac (2015) crash all the time and it take 5 minutes to open my different softwares. I must install it now it been 24 hour of hell. Every time I click on the uninstall button for Creative Cloud an error come up to reinstall and I done 5 times now and still can't remove it. I must get this away now. Adobe you costed me 2 days of work....

[Moved from Photoshop forum to Creative Cloud Download & Install forum by Mod. Might also get better answers as to why it is crashing]
