*I think this should be a code amongst all anxiety & panic disorder sufferers.*
We've all been there before, freaking out over something that has us worried, which in return we head to our closest smart device and hit the web in search for an answer to our problems. Only to find that the answers you get just make your anxiety 100x worse.
I speak for everyone when I say looking up your symptoms on google is the worst thing you could possibly do, I made the mistake of doing that and called the ambulance on myself once when I was completly fine.
If you really think it is that bad, go to your doctor and get a checkup.
In the mean time, try and relax, breathe, drink some water, and remember !
