I know this feeling is normal when going through severe anxiety, but I need to be reminded, and reassured a little.
I feel like I am going to go crazy. The anxiety builds and I am 100% sure that I am going to lose all sense of self and not remember a thing about my life. Like it will happen suddenly and I will go from (vaguely) sane to completely gone.
I know many will be able to relate to this, but I have this tension at the back of my head. It's to the left hand side and feels kinda of like a ball of tension.
This bit I do not expect many to relate to

It feels like THIS part of my head is the part which contains the "crazy", and when I start to panic I think that the sensation that is there will spread throughout my whole brain and cause me to completely lose it.
I know it irrational, but when I'm panicking and on edge it feels true. And I'm on edge a lot.
I'm not expecting anybody to tell me much. I think just saying it out loud (so to speak) may help.
