Overthinking has been a big problem in most of the peoples life. Gives you a negative attitude, affects your relations with friends, family etc. How can you possibly stop yourself from overthinking when probably you have no control of what to think?
start believing in your self and believe in what you can do on your own , sometimes or most of
the time is that overthinker people are those who has lack of trust to themselves that is why they are thinking
of what can happen here and there , I use to be the same but not when i learn the basic to love myself and trust it.
