To me, the key thing is what you are doing outside of sessions to support yourself, and whether you feel alone in that or supported by your T.

Example, let's say it's in between sessions and something comes up that triggers your or stresses you out.

Scenario one, you feel you need your T, and you can't get in touch with her soon enough. You question whether she cares. You now feel abandoned in addition to distressed. The next time you see your T, you're angry at her about this.

Scenario two, when you feel distressed, you remember the conversation you had with your T about what to to in between sessions when you get triggered. You even pull out the plan you made together for how to cope. You email or leave her a message and feel confident that she will reply within the next 24 hours. In the mean time, you follow the rest of your plan by calling a friend, journaling, listening to soothing music, listening to a voicemail your T recorded for you, or whatever else you decided would be helpful. By the time your T calls you back you're already feeling mostly better. At your next session, you feel proud that you and your T together helped to get you through that.

It also matters how you work together to pace sessions so that nothing happens in a session that isn't dealt with before you walk out the door. You shouldn't be leaving with that feeling of "what just happened?" Even if it means stopping 15 minutes early to process, see if there are any stray feelings lurking around, making sure you're not dissociated, and taking in some connection before you have to go.
