What is your IC saying about what's going on with you, right now?
Do you have an emergency number for the IC?
I'm not overly worried about you atm, DIM... but you do appear on the edge and while you are venting here, which is well and good... you sound like you are stuffing it down IRL...
But it does worry me about your D... I'm sure you are taking care of her basic needs, but what is your plan B in case you really do need to check out for a while with some down time for you?
You're going on that trip, right? Or "outing" as you called it... That should help.
You talked about your meds... have you gone through a review on them?
