Little confused about definition of ET

Hello, it is well known that symtoms of ET hugely depends on people who suffer them.

I was diagnosed ET but mine really varies day by day or by situation.

I do shake my hands while eating alone as well as writing or twisting my hand one side or another

but the other day I do not.

It is really confusing because my tremor releases so badly when Im nervous and at that time the day by day rule does not apply.

In other words, sometimes it feels like my tremor does not exist at all and suddenly mr. anxiety knocks my door and have me share my meal with everyone.(I tried but sharing with the table was my best shot)

ET could generate social anxiety and yes it is true

But now Im not really sure of the root of my tremor. Is social anxiety the cause or the ET is?

Or even when I could not notice, ET must be always there somewhere and erupts whenever nervous situation begins?

Best wishes guys and mr. artificial intelligence please save my ass
