This isn't really the place for this, I don't think. This board is for erotic roleplay, of which this is neither erotic nor roleplay, according to the op stating it as "an original story" "and no it's not smut"
And your grammar is so awful it makes me not want to bother, and what you really need is an actual English class or two, but here: I did the first paragraph for you.
In red, your original
<My name is Elizabeth two those who around me I am Lady Elizabeth, I came New Kandinsky about two weeks ago, I don’t live here just simply visiting. Back home I am known by the dumb Local god fearing yokels, as a Witch, Monster, or Demon, while the last one being the truest my intentions are not same as the other’s who share my title, though few do these day’s I am a true demon, few get to call themselfs this.
And in green, my correction/interpretation
>My name is Elizabeth, but to those around me I am Lady Elizabeth. I came to New Kandinsky about two weeks ago, though I don't live here, I'm just simply visiting. Back home I am known by the dumb, local, god-fearing yokels as a witch, monster, or demon. While the last one is the closest to being true, my intentions are not the same as others who share my title, though few even do these days. I am a true demon. Few get to call themselves this.
Look back and forth between the two and see what I changed. Figure out all the things you did wrong, and then continue on to my explanations below since you are likely to have missed a thing or two.
"My name is Elizabeth" is its own thought, and requires some form of separation from the rest of the sentence. In this case, a comma.
"two those around me" is the wrong form of "to". "Two" is the number between one and three.
My name… simply visiting" deserves to be two separate sentences. One stating the name, the other talking about the location. I'd also consider getting rid of either "just" or "simply". It's unnecessary to have both and it would flow better with just one. Take your pick.
"I came New Kandisnky" I assume you're coming to the place, but since you left the word out it could be from.
"I don't live here just simply visiting" needs some sort of separation between "live here" and "visiting". At least a comma, I added in that specifically "I'm" visiting.
**"dumb local god fearing yokels" when you're making a list, including listing out adjectives, you need commas between the items. "Local" has no reason to be capitalized, and since you're using people who fear god as a single word, you would need to use a hyphen and make it "god-fearing"
"a Witch, Monster, or Demon" even though these are names you're being called they're not actually being used as names, but rather as descriptors, and thus shouldn't be capitalized. If you removed the "a" from the sentence and made it "known as Witch, etc" then Witch and the like would be considered proper nouns as names, and would be capitalized
In general, this is a huge run on-sentence. Take a break, use a period. I put one after the name-calling
"while the last one being the truest" is just really awkwardly phrased. I can't point to any specific rules, but it just is.
"few do these day's" don't use apostrophes on plurals. The apostrophe will only pretty much only ever denote one of two things: It's a contraction and the apostrophe represents some letters being left out (though in formal writing you're not actually supposed to use contractions) or: It's showing possession, such as "the cat's pajamas" saying that the pajamas belong to the cat.
"themselfs" is not a word. "Self" is singular, and when made plural it becomes "selves". Same thing with Elf and Elves if you ever plan on including them, I don't fucking know
Oh, and when writing a title, capitalize pretty much every word that's not an article, so your story should be written as "Behind the Mask We Share"
Your posts have grammar that's at least as bad, too. You really should at least learn the difference between "there" "their" and "they're" before attempting to write anything
