I think often its not a case of stopping the thoughts because I don't think it can always be done, but rather trying to act in spite of them so they don't always have such a strong holding power over you and trying to do your best with the hand you've been dealt, again something easy to say but incredibly hard to actually do

reminds me of the lyrics of "the grudge" by tool which is all about how people cling to grudges and how they confine you and drag you down

Love the last part of the song:

Give away the stone
Let the ocean take and transmutate
This cold and fated anchor
Give away the stone
Let the waters kiss and transmutate
These leaden grudges into gold

Let go x33 (crescendo)
