Sorry, I completely disagree. It is your therapy, by design you are at the very center of it. Your needs are the only ones that matter. You don't need to look after anyone's needs bar your own. That isn't selfish, it's self-care. And if you don't have self-care you have nothing because you cannot possibly look after anyone elses needs if you yourself is drowning.

Ask yourself why you're putting the needs of a) someone that you don't need to look after ( your therapist) and B) Someone you don't even know and have absolutely no responsibility for. Before your own needs?

Martyring yourself doesn't help anyone. You deserve to look after yourself. You NEED to put yourself first. That's what self-care is about.
