What's the difference between hypersensitivity and auto-immune disease, within the context of immunology?

What's the difference generally, and specifically?
-if you can confer examples that would be great.
a hypersensitive reaction is the body's overreaction to an outside invader. IE: bee stings, shellfish, etc.
an auto-immune disease is when the body mistakenly recognises its self as a foreign invader IE. lupus, rheumatoid arthritis etc.
A hypersensitivity allergic reaction is an allergy. This is when your immune gives an indecent response to an antigen. This is when the antigen is now call an allergen. For example pollen does not affect me, so pollen does not cause an allergic impulse and thus to me pollen is not an allergen. For people beside hay fever pollen cause the immune system to go into overdrive and cause the allergy. So to a person next to hay fever pollen is not lone an antigen but also an allergen.
Our body cells also hold antigenic markers on the cell surfaces. Our immune system must know how to know that those antigens and markers are you and not some foreign invader. An autoimmune response is when your immune system begin to attack your own bodies cell markers and treats your own cell as a foreign invader. Many examples include, Lupus, Rheumatoid arthritis, psoriasis and the list go on.
