Sensitivity to light and sound, sensitivity to cold, feeling wired all the time, racing mind, OCD tendencies, insomnia, severe weakness, irritability, panic attacks, bed ridden
If you have a combination of the above symptoms you have spiraled downward. This is a mind problem. Your mind has become very sensitive.
You get here because of feeling frustrated, hopeless, worried, fear, overwhelmed, etc. Basically you are getting deeper and deeper into a sympathetic state (nervous system).
The stress of day to day life will have minimal impact on you but feeling the reactions I just listed are what will get you to where you are.
You need a timeout. Take a break from the forums. Have faith your body will get you better on its own because it will. Casually observe your mind and catch yourself when you are feeling unnecessarily fearful. Eventually, you will become less and less sensitive. If you wake up and feel worse than you did the day before, don't panic.
After a few weeks or longer, most or all of the symptoms I listed should be gone or greatly diminished.
