I am so sorry you are struggling. I hope your pdoc gets back to you soon, but please keep yourself safe. I will say this: a pdoc recently told me to be careful with Klonopin, because there's some data that in certain individuals it can exacerbate SI. Just letting you know, but of course, you can talk to your pdoc about this possibility. Lately for me, Klonopin sort of dampens my mood and makes me groggy.
Take care of yourself and keep posting whenever you feel the need.
