たすけてです！ーー この、これ、反れ、そ

[Sarius24]

たすけてです！
I'm really getting confused with これ、この、その、それ、あの、あれ、どの、どれ！
Like what do they all mean? whats the difference between them!
They are so confusing and how do i know when to use them?

All of these sets (which go further than your examples, extending to things like こちら、こんな、etc) that starts with こ refers to things close to the speaker. Any starting with そ refer to things near the listener (relatively. It's subjective, there isn't a measurement attached). あ refers to things far away from everyone involved. Again, it's subjective. That could mean on the other side of the room, out of site when refering to a building, or another country when you're talking on that scale. You also use そ words when refering to things previously mentioned, pretty similar to how you do in English.
ど words are questions. "Which?"

They're commonly broken down into こ　this, そ　that, and あ that over yonder. Only for your comprehension, of course. No one in English uses 'yonder' anymore..

and just for a quick list

これーthis (noun form)
このー this (adjective form)
それーthat (noun form)
そのーthat (adjective form)
あれーthat over there (noun form)
あのーthat over there (adjective form)
どれーwhich (noun form)
どのーwhich (adjective form)

and by noun form and adjective form i mean:
これはたのしいです = This is fun
In this sentence "これ" is a noun
--What is fun? this is fun

このえいがはたのしいです = This movie is fun
In this sentence "この" is an adjective describing "えいが"
--which movie? this movie

Except for old Southern grandpas and I think a random dialect in the UK.

I live in the area of NC that's becoming the new Silicon Valley (Raleigh/durham/greenville area), so most people don't have accents anymore, but there's still many who do. And my grandfather.....sometimes, I can't understand him. Haha.
