Reflexive pronouns (self pronouns)- refer back to a noun in the sentence and usually follow a verb or preposition.

EX:  John wanted to read the book himself.  (himself refers to John).

       I drew the picture myself.  (myself refers to I).

      We heard her say it ourselves. (ourselves refers to we).

Don't use a reflexive pronoun if the sentence doesn't have the noun it refers to.

WRONG:  She cooked dinner for Bob and myself.  (you can't use myself because it doesn't refer back to any words in the sentence. Myself isn't referring to she or to Bob.)

RIGHT:  She cooked dinner for Bob and me.  (for is a preposition, so you need an object pronoun to be the OP.)
