Hey there...

I am thinking it might be a bad idea. However you could ask him for a few extra sessions to see if you could work through the things you want to work through. I have done this with my therapist. I was really manic and emailed her at 3am and gibbered on a lot then asked if it was possible to see her extra. She asked me to go in 1.5 hours before my actual appt so I had 2.5 hours that day. We made it for 12:30pm instead of 1pm after that and finished at the usual time of 2pm.

Unfortunately this only lasted 4 weeks as COVID-19 kicked in. But through March-May she called me twice a week and we are since May ish to currently just speaking once a week.

I too am attached to her so tbh this has worked out great.

If you and your therapist feel you will be OK then try extra sessions there is no harm in trying is there. But if you feel or he feels it would be too much then respect that. Maybe he could just five you extra time on your original session?
