A mindset/mindfulness technique is to acknowledge your thoughts.
However, there is a problem with this if this is all you do…
I great first step when acknowledging is to classify the thought.
An easy way is to use GRUB (food for thought)
So a GOOD thought is one that is positive and nurturing.
A RUBBISH thought is a waste of time thoughts like bad news, gossiping or repetitive thoughts.
USEFUL thoughts are the I must eat, go to sleep type thoughts.
And BAD thoughts are the destructive and negative thoughts like I’m no good, I have no influence etc.
Once you categorise them you can decide to let the Good and Useful in.
Rubbish thoughts you dump (which will take multiple times).
And the Bad may need a little bit more work with however the underlying root is an unfulfilled ‘want’ or desire.
Identify what it is and reprogram it.
Give this a try and it will definitely reduce the overwhelm and give you more control over your thoughts.
Keep smiling and speak anon.
