The problem with a mental illness is you can be fine for a while. Just completely and totally functional like a normal person. Then for no reason whatsoever you feel that overwhelming feeling of hopelessness, sadness, or worry. And it feels like you’re just back to square one. The sudden feeling that you don’t matter always comes back. The worst part is you can never explain to someone why, it’s just how your mind works.
