What is happening is your anxiety is getting more out of control. You need to seek professional help to start addressing it.
Update us after you've seen your doctor. Anxiety is very treatable, but it is not something that will typically get better without help.
I understand, although I don't fear crowded spaces, or the toilet. I am absolutely terrified of heights and bees. I cant stand being to high off the ground or i start to hyperventilate. And when there's a bee near, I either run away screaming or start to shake with fear. But what I do is try to convince myself that I'm not going to die, an I try to regulate my breathing. That's what I suggest to you. Better yet, you should go see your doctor, and see what they have to say. I'm sorry to hear about your phobia because I know it *****. An good luck to you.
