The customary practice in New York City, and elsewhere, is that a person will sit down with a (one) therapist for a 50 minute session, so your experience is a bit out of the ordinary.
There are therapists who specialize in trans gender care, and this is the kind of person that you need. Most therapists do not have the training, the sensitivity or the understanding to be of any help. You want someone who can work with you to help you to understand why you have the feelings that you have. Not all trans gender or gender variant people are TS. Most aren't. Not all people want or need to pursue HRT. You need to work with a trained professional to help, not hurt you. The wrong person, or the wrong kind of therapist, as you've found out, can do more harm than good.
