I don’t think it would be at all needy to send a follow up. I don’t know what you should do about choosing to see him again, but I would probably be inclined to send a follow up, and determine from that reply how to proceed. Though I realize it’s very stressful with a new person, so I think it would be reasonable of you to cancel if that’s what you felt like doing.

My therapist is really great but he sucks at replying to emails or texts, and I often have to remind him. I don’t mind, partly because I also often forget to answer people! And also he’s an excellent therapist despite this flaw.

I am sorry that this is happening though, and I wish for you that he would have just responded in good time!
