Hi there, ShockedShattered. I'm so sorry you're going through this nightmare.
Before I answer your question, please understand that what you're experiencing is quite normal. The betrayal of infidelity is a profound shock and a severe emotional and psychological trauma. It hits hard and it hits deep.
If I remember correctly, it took me a few months to recover from the initial shock. I lost over 30lbs in about two or three months (of course, those pounds found me again). Try to eat small, healthy foods whenever you can. Even if it's just a couple of carrots, a bagel or some eggs. You need to keep up your strength.
Sleep was also elusive. I tried a mild OTC sleep aid. It worked, sort of. It's just that the anxiety was constantly there and even a good night's sleep didn't help that much. I'd suggest making an appointment with your PCP and let him/her know exactly what is going on in your life. Chances are they've heard it before and can make some good recommendations.
We often talk about the "rollercoaster" around here. It's a shitty ride! Constant ups and downs and twists and turns. My emotions could change at the drop of a hat, from bawling to rage, bewilderment to moments of clarity, from a desperate need for connection to feelings of utter revulsion... all in a single evening.
I couldn't function. I'd go from one room to another with purpose and by the time I got to the next room I'd forgotten why I'd gone there. I'd start a simple project, like unloading the dishwasher, and end up side tracked and completely forget what I was doing.
All of this craziness is a perfectly natural response to the shock and trauma.
It does get better. I promise. You WILL recover. It just takes time.
Posting here helped. Talking to an old friend who had gone through something similar also helped. Taking long walks or bike rides in nature helped. Hitting the gym helped. Journalling helped. Breaking shit helped.
Time helped.
You'll get there, sister.
Focus on you.
