What you are, instead alive, is a walking dead, resigned, and settled for the little that, it seems, life has to offer. To you. You see others, seemingly happy, seemingly alive, and you feel regret, shame, and envy.
Your heart, where rain forests and colorful birds, and life used to live, is devastated. The lush rain forests gone, the birds gone, life: gone.
Your ups and downs are tiny, not like a roller coaster. They are about money, or noise, or that you are fat, or skinny, or that you are aging. Irrelevant circumstances.
Maybe it is about someone being sick, maybe dying… but that is also a circumstance.
