I am worthless or even a burden by economic point of view, but when it comes to family I am priceless. I remind myself that my mom, dad, brothers and a sister love me unconditionally. They are the main reason why I am alive right now. I am cursed by their love, and at the same time fortunate.
I check if there is a silver lining of some sort, or if the beliefs I have are true with no contradictions. I may be worthless to 99.99% of the population, but I have something or someone to live for right now.
While it may not be the same for other people, there may be someone cares for them. For instance, there is an advocacy group for societal "rejects" for current or former inmates who has nobody to love them. These advocates really took their free time and money to devote their lives to these "worthless" people for rights of inmates, educating the population about convicted persons, ending death penalty or engaging in charity work for their future release.
You may think that you are worthless, but here on SS, we treat you as if you're one of us. If you are truly worthless, nobody will respond to you because you are not worth their time.
