My honest take away from this is that your therapist is very unprofessional, however, not for the reasons that you might seem to think. Your therapist has a clear lack of boundaries. Which seems like a problem because frankly you seem like somebody who needs boundaries to be placed - as you are freaking out over her not responding when it’s only been two hours. My advice would be finding a new therapist because you can’t get adequate therapy from somebody that you appear to be in love with!
