I am not sure I would describe the state as addiction, but I think everyone who posts here has a preoccupation, obsession, or attachment to therapy (if not a specific therapist). Even the people (especially the people?) who are very vocal about their anti-therapy views have a very tight relationship with therapy, I guess irony isn't a thing for many people.

I feel addicted to the idealised concept of therapy and my therapist. The reality of her and the sessions are often a bad trip. And the withdrawals are hard, I agree.
