OK, thanks everyone for your advice. I really had wanted to get something, but I understand now why it might not be the best idea with a therapist. But the reason I really wanted to get something was because I didn't want to come off as rude like I didn't care about
it, and giving a gift is my silent way of expressing how thankful I am and appreciate of them.
Problem though, I'm a horrible writer so I have no idea what I would write! I know it's hard asking for help writing a personal letter, but I honestly am horrible at it. But i would like to do it.
