Imagine being pushed under water, like someone is sat on you, holding your head under water. You're kicking and screaming, feeling out of breath and your heart is racing.
That's anxiety. You're drowning, and there is no one there to save you.
That's what it feels like for me, every second of every day my heart is racing, beating faster than my body can produce oxygen. Every waking moment is consumed with worry, over trivial things most of the time, but all of that is heightened into gigantic proportions. I'm constantly on edge, wondering what's going to set it off next.
Because of this, I constantly need reassurance. Reassurance that you're not leaving. Reassurance that we are ok, and reassurance that I'm safe.
