Just because many people are struggling with remote sessions doesn't mean it isn't difficult for you. Post as much as you need and as repetitively as you need. Something might shift as you continue to write about it.

Are there some practical things you could do to bring your therapist into the room with you? For example, I light my oil burner with an essential oil which has significance for us. Maybe lighting a candle? Is there a texture or material which you associate with your therapist or therapy? You could hold that during session. Is there a particular drink you would take to therapy or have before/after session? I would think about the different senses and how you can soothe those senses during a session.

Keeping the connection live and close is not easy. Would you feel comfortable talking to your therapist about what you DO remember about them or their presence?

I haven't struggled with remote sessions, I prefer them because they suit my (historic?) need to remain distant and protected. I remember her physical presence fondly though and sometimes wonder if I would like to see her again.
