To have ANY chance at some lasting peace, you'll have to stop googling - period. You already know everything you need to know, by now, anyway. And, you know (through googling) about too much stuff that doesn't even apply to you - such as 'living with MS', perhaps. You do not have MS. You'll accept this, to your own personal extents, eventually. I can't say when as I can't say when you will begin to fully embrace all the actions and habits that can, ultimately, lead you to having anxiety not be as dominant in your life. Even when we are doing all the 'right things', we still will have some crappy interactions, at times, with anxiety. There will be setbacks...it is the nature of anxiety disorder(s) / health anxiety, overwhelmingly.
All you are doing by internet searching is cementing, in an anxious mind, the notion that there is a definite possibility that the MAJOR reason you are struggling, overall, in your life is due to a sinister health issue. All an anxious mind needs, very often, is a possibility to keep us locked in a cycle of fear. But, in the end, there will always be a possibility, of this or that happening on our lives. "What ifs?" abound when we are struggling - I understand. But our actions so matter in KEEPING us locked into fear cycles, when maybe, if we were able to stop a counterproductive habit for a good period of time, we might be able to loosen the grip of anxiety (just enough:) where we aren't panicked into further counterproductive actions / habits.
An action can be NOT doing something (a bad habit), also.
Trigeminal Neuralgia? Absolutely not. You are struggling with anxiety. Don't get me wrong....struggling with anxiety can be an amazingly, crippling experience....I have been there - to the 'edge', so to speak.
Clear MRI / clean blood / "all clear" Doc exams = you needing to move away from thinking about more medical intervention and beginning to focus with all your available energy (calmly:) and your resources on learning how to accept and manage and live well with anxiety. It most certainly can be done - living well alongside our anxiety issues. Easy? Nope. Challenging? Sure. Worth every bit of effort and sweat and tears? Absolutely:)
What's going on in your anxiety treatment?
Peace and Feel Well:)
