I leave my camera on but make it so I can't see myself, far more immersive. I try to pretend I'm in front of them in person.

Also I recommend you forgive yourself/others for getting distracted. If you were getting coffee together, you'd frequently get distracted by the surroundings and ask the person to repeat themselves. It's not like you're in a therapy session where you have to pay deep, undivided, focused, uninterrupted attention on one person over an hour. That's really hard.
