Sometimes I question whether my life’s worth living

It’s not as bad as it was before but there is never a week that goes by without me questioning whether I’m even worth anything to anyone around me. For a time I truly believed that I wasn’t worth anything and that I was a nuisance to everyone around me and that the world didn’t need me. I’ve seen all these online articles about how the world needs you when you’re questioning your worth but during this time I felt that the world would have been better off without me as that would’ve been one less resource sucking carbon-emitting sack of organic molecules. I’ve heard from others like my parents that I’m not a nuisance, but it’s kind of hard to take something like that in from my parents since they are partially responsible for why I’m suffering from emotional numbness and depression. I’ve heard people argue that the world would be a much different place without me, but the science part of my brain argued that the world will continue spinning on its axis and revolving around the sun without stopping, slowing or altering in any way, meaning that the world as a whole will still be the same, whether or not I disappear. When you have that kind of perspective it’s pretty hard to even take in ideas like how the world will be different without you. Usually, you see something positive at the end posts like these, but I’m just too depressed at the moment to say anything positive or reassuring to anyone reading this, so I’m sorry in advance.
