Tattoo area?

So I want to get a tattoo for my 18th birthday. I’m one of those people who can’t stand needles and freaks out when getting a shot. But I got my belly button pierced and it didn’t hurt at all and I didn’t freak out. So I was wondering where I should get one that won’t hurt very bad. I wanna get one with words for my best friend who died. I had thought about getting one on my ribs but I heard it hurts. So I was thinking about on the back of my shoulder or like under your shoulder on you’re back. But I want it somewhere where like it could be covered easily if I needed it to
