BS here...hope it's ok to post. Kudos for recognizing the reasons you are triggering and wanting to reach out to your AP. That's a big healthy step.
Can you talk through it with your BS? I would let him know first and foremost that it isn't your AP that you are missing or interested in talking to, but that there is an uneasy feeling inside of you that is making you want to do something that you don't really want to do. I think sharing this with your BH might start a good dialogue.
Can you move your IC up by a week? I think when you are going through something like this you need to arm yourself with all of the support/resources you have so you can get through this.
I'm sure some other WS' will come in with some better advice, but just know that recognizing the triggers is a big step and posting here when you have the trigger is another healthy decision.
