It may be the therapist moving the chair away, but it may be for reasons other than the ones you immediately go to - and it could even be to make clients feel more comfortable (ones like me - I did have to tell the one I see to stay back away from me because she kept moving in too close) and not to punish clients (how it feels to you). OR the chair placement may well have nothing to do with you at all. I believe you do have the strength to tell her about this even if it is not easy for you. Is the pain of telling her any worse than the pain you are in right now?
