Sarah, you don't know that's what happened. Iirc, your therapist had given you more sessions than she was allowed to. When she sought supervision from her supervisor, this came to light, and the supervisor, who didn't know or care about you, saw no reason for you to receive special treatment (meaning more sessions than were allowed). That scenario sounds like something that could happen very easily to me, particularly since you were utilizing free services. Oftentimes organizations offering free services, such as rape crisis centers, centers for lgbt issues, etc. have a session limit so as to be able to help as many people as possible. Your therapist should have been clearer with you that she couldn't help you indefinitely, but you haven't mentioned anything that suggests she ditched you because you were overly attached.
