All I wanna do is pvp

Like the title says…all i wanna do is pvp. Randoms, rated it doesnt matter to me. Im also too old to have the lightning quick reactions of some of yall. I want to give healing a shot but I need something thats super simple for an old man like myself. Maybe even direct me towards a healing macro on this site for any of the healing classes that works well. I will post this in each class that can heal. Thanks in advance.
