Little Unknown Box

I almost feel bipolar. One day I’m completely content with my life, and very happy to be here. The next I don’t understand why I even want to live, and that there is nothing great that I will amount to be. I feel like theres something little in my brain that I can’t understand thats causing the malfunction, like a mental block. I would never tell my parents, because from the outside, my life seems perfect. Yet I feel like I’m dying on the inside and can’t tell anyone; because why would anyone like me feel this way. No one would believe it. I almost want to say that theres something wrong that I’m thinking about, I have a road block on how to look on life. I can’t even form words for what I feel sometimes, its not anger or sadness, it confusion and lost.
