Answer:
Hard work through intensive effort.
Explanation:
The paragraph talks bout the hard work synesthetes do, which tire them down. Hence, "Hard work through intensive effort" is the meaning of "Stimulation".
It means that if you do not speak up about being depressed or "in pain" people around you that you interact with will unknowingly kill you on the inside and when/if you speak up they will assume you enjoyed it because you did not speak up before. Its a metaphor you see... if someone were to continuously stab you and you didnt speak up, they would stab you to death and assume you liked it for not acknowleding your pain.
