If the therapist gave it to you, then don't worry about it. Let her and her other clients work out what they need. If she is not a cruel person, then presumably she would not have given away something that would cause someone else to be inconsolable in general and if someone else was needing a stuffed item, the therapist probably was able to handle it with that other client.
There are people on this board and others like it, considerably older than you, who have spoken of their stuffed animal comfort objects.
