How do I help other people understand that my sadness is not their fault?

You could have a conversation with that person so theres no misunderstandings.

If one is to be technical, sadness is a cycle of loss or lack. Where there is something missing, or you miss something or someone, or perhaps just apathy and emptiness. Where one feels like there should be more, that there could be more. Society says “pull yourself up by your bootstraps” and to “help yourself,” but how can anyone know how to begin? The world has existed long before I did, and will hopefully exist long after I pass. The way the world was when you arrived is out of your control, so you cannot blame yourself for how it is right now. The world, in a word, sucks. You are allowed to feel wronged. If you aren’t ready now, that is fine. If you need a minute, or a month, or your entire life, it is a good use of time to find yourself and reflect. As long as you are doing something, you are doing your best.
