How to hide or make really pink scratches less noticable?

I wouldn't call myself a cutter but I snapped one day and lost it I thought I was going crazy. Anyway I grabbed the nearest sharp object which happened to be scissors and strached up my arm to relieve some stress. I have never done anything like this and i need to hide them from friends and family. I am already getting physcological help so it isn't a big deal they know about it. I can talk to the therapist about it. I just need them to be less visible or look atleast make it so it isnt so obvious I did it myself.... I might just have to resort to long sleeves even tho its getting warm out.
