Burnout? I think I may have it

Prior to a post I made, I have been doing some research, and I think the conclusion is that replies made to me were correct- I may be suffering from autistic burnout.

I can tell you, horrible doesn't even begin to ponder on how it feels. At times I feel like a tornado is swirling in my brain, not being able to process anything and barely using enough energy to the most basic day to day tasks like getting out of bed, making myself breakfast, calling someone etc. What is even worse is its affecting my whole person. I feel like I am losing my interests and parts of my personality which makes me... me. I am absolutely terrified of the effect its having on me and I can't bring myself to tell anyone about it. Partly because they will not understand and partly because I'm scared that they might not take me seriously. I am trying desperately to think of ways to combat this. I don't want to lose who I am.

Please help.
