Are we supposed to feel this way?

Sorry for all these posts,
I feel I use half of my brain—one side. I feel one side of my brain is neglected—my brain is active on one side not on the other side. I’m using my right side but not my left side which is odd because my portion of the brain tests show I’m more a left-brainer than a right-brainer. It’s almost half and half but we humans don’t use all our brains. We use half of it, portions of it, rather, and we cannot think more or use it more than we should because it’s different. We are not perfect.

What I want to give out is that the brain portion I’m supposed to use isn’t working which is why I feel like I’m mentally handicapped or something, stuck in something I can’t get out of.

Update: When I want to think or use my brain, it doesn’t work, properly. Idk, I feel I’m supporting my head with something inside it—a big glob.
