When I use?

[Anonymous]

I would like to know when necessaraly I can use:

I, ME or MYSELF
Is there any specific rule for that use?

[RonBee]

Use I as a subject, me as an object. Use myself as a reflexive pronoun.

• I did it.
  She helped me.
  I did it myself.

Use me as the object of a preposition.

• Is this for me?
  Let's keep this between you and me.

Do not use me as a subject. Always use I.

• Sharon and I went there together.
  Bob and I went to the football game.

Use myself to refer back to the subject. Note its similarity to himself and herself.

• Bob did it himself. He didn't have any help.
  Sharon has been talking to herself.
  I caught myself talking to myself.
