This is very simple advise. It can be hard to do at first but trust me, you'll be a lot happier.
Stop googling anything and everything related to your physical or mental health. Stop. Totally stop. Don't google that anxiety symptom. Don't google that disorder. Dont google that strange rash.
Stop Googling
Your are not a doctor and neither is Google. Its only too easy these days to get your phone out and make a search. To find other people who have felt the same weird sensation. To search for an explanation.
But, none of these things will stop your anxiety. By searching for an answer you are allowing that thought path of worry to continue. Is spending 20 minutes researching that weird sensation really helping you? No its not. It's giving in to an impulsive thought which will be something like "I need to know what this is."
No. You don't. 99.9% of the time it is absolutely nothing.
Don't Google it. Just let it be. Accept it.
And if you have an actual health problem or concern GO TO THE DOCTOR.
STOP GOOGLING. It's an addiction you never even knew you had. When you stop doing it notice how uncomfortable it makes you feel and you'll realise how trying to "find an answer" for everything is so addictive.
There is no answer for every sensation, thought, feeling. Just let it be, let it pass and get on with your life!
