Very controversial, but sometimes letting go of something is the best option although it does not seem like it on the first or even second thought.
But taking the decision is strong of you and you can totally do it.
Trust yourself and stand up for your decisions.
One very last tip, pretty random, but:
"Don´t make one thing your everything"
I had to learn the hard way and just take a moment and think about it.
Maybe you feel the same, maybe not and that is totally fine.
"To let go"
A verb meaning "saying goodbye"
Or does it mean "see you soon"
It probably is a combination of both
Does it hurt?
I can answer this;
Definitely YES
Does it feel good?
Weirdly yes and no:
It is question of guilt and relief to answer for yourself
Why do you let go although you love it?
Simply because I love it too much
Yes that is possible
And in the end, overachievement can destroy
Perfection can destroy
Destroying the thing itself for yourself
Destroying the pleasure
And the reason why you love it
