Arte, I'm really pleased that the lady is coming up to see you about this. Even though it's confronting for you, it will be reassuring to talk to someone about it. I hope you come away with some specific strategies to try and also an offer of ongoing contact if you need it. In the meantime, try not to stress over it. It's just a thing. Plenty of people have strange little soothing behaviours, some of them are more common than others (thing nail-biting, for example) but it's just a small part of an otherwise full and balanced life.
