Not fully human?

First of all, dont read this unless you are sure you won't call me crazy.

I feel like there's something else in me. I have the natural power to heal plants and feel their pain, or whatever you call what i sense as pain in them. Thats the main reason i suspect it. I can also be out in 100 degrees fahrenheit and not sweat for hours or burn at all. Dont call me crazy! I cant say anything to my parents cuz they dont believe in what they call "stupid myths" and my bro is too skeptical

You are and will remain biologically 100% human just like everyone else.
