First, I would be just as upset if I asked for support during a session and it was denied. Following up with a text was probably doomed to not be any better than what happened in person, but I would try not to jump to seeing it as that he hates you. It sounds like he's not at his best (not sure what his best looks like from here, but this does not sound even in the ballpark), but it's 100% about him and the fact that he can't shed his own issues to be there for you.

Honestly, I don't get why a therapist would refuse support in any case, but after 5 minutes of getting a no in person, this one probably needs time to get that giant stick out of his southside before I would approach him. Can you distract yourself for the weekend and then revisit what to do?
