It sounds like you are communicating and that's good.
My system has and internal force that has alot of insight to the inner workings of the system. She talks to our T and will guide insiders as far as grounding and finding better places inside to rest and gain strength.
She also will give warnings about "storms" coming. She usually will tell T that someone needs attending. She is very cryptic and usually right about things.

As far as antianxiety meds, I didn't have much luck. Made things worse and so I stopped taking them. My Pdoc now has Naomi (who gets the most anxious) on a strong antihystamine which will make her sleepy and rest. Usually if she does that someone else can handle the situation or when the body wakes up, someone else is in place.

Learn your grouonding techniques and make sure you have a safe inside place and much support that you can call on. Know who the more "stable' of the insiders are and arrange for them to take over when things get really rough. We're learning that with Naomi right now. It's a struggle, but it is keeping the body safe when she panics or gets SI urges.
Here to listen, PM if you want.
