When I read your post I thought - Oh, my, that's me!
I had such a hard time so I truly understand and feel you - never having anxiety before, ever, never having blood pressure problem before, on the contrary, it was always normal to low. But then came the wd and left me speachless. I wasn't even able to write anything here for months, to reach out even. As 25 days are tangible and true accomplishment, there is a chance that you will have to endure a bit more of unplesantness. A month is still acute wd. For me those symptoms lasted for around three months but they get easier and easier from there. What is so awful when you are in acutes, is inability to imagine the future being different, but it is different and better. You'll see.
