Getting over Therapist

I have been seeing a therapist since 2019 and it was my first experience with one. At first, I didn't like it but I grew to love it and loved talking to him about anything. It just felt so good to talk to someone without judgment and someone who cared about me. He is now moving away and I am devastated. I'm trying not to be sad but I can't seem to stop. Idk what I'm gonna do now that he's leaving and truthfully I am hurt. I didn't think it was gonna end, I feel like I'm going through a breakup. I can't help but wish I didn't meet him now so I wouldn't be in this much pain. Idk how to process this hopefully someone can help.
