"I feel 30 times is very short, so short that I don't even want to open up to my therapist because it will end soon." I'll feel the same as well, I would interpret it as they are just throwing me a 30-session package and just say good-bye when time's up, like there's ingenuity behind it.

It is free, and I believe any time investment in it will only allow you to know the answer compared to speculations.

May I ask, if you have been there and completed the full 30-session or you left half-way before?
I think it's an important thing for me to understand more from you about this package.
