I've been bothered with how mine ends lately as well. My therapist goes an hour. He explained in our last session how he always had 60 minute sessions then cut it short at 50 minutes. He starts every session late, so even though I walk out of there an hour after our official session, because he shows up 15 minutes late I see him for maybe 45 or 50 minutes. The whole thing is making me hate myself. I suppose we never end abruptly because I'm so bad at speaking I'm usually mute for long chunks of time, making it very easy to just stop talking to me.
