I've been sitting here for about 20 minutes reading this post over and over trying to think of a good way to respond to it and currently I am very worried, for lack of a better word. Why would you think that nobody cares if you left this world? And I'm glad that you are thinking about the pain it could cause but truth be told, the word you should use is "would." I am sure there are many that truly care about you, and while I don't know you IRL I care about what happens to you and please don't say this is all you are good for. There are many things I'm sure you are good for. If you are truly feeling like you may do something please call someone, a family member, a friend, a crisis line. This is not your calling. You were not brought to this world to end it. You are a worthwhile person so please take care of yourself. You are meant to be here.
