Self-dramatization is important. The following activities will express your ineffable singularity:
Write execrable adolescent angst poetry. Spelling counts: Be sure to get it wrong.
Write incoherent short fiction in which the protagonist (who resembles you) dies at the end, and they're all sorry now, aren't they? Again, spelling counts. Be sure to transpose "your" and "you're". Use sed if that doesn't come naturally.
Listen to The Smiths while feeling sorry for yourself. Nobody ever did that before. That's why nobody really understands you.
Call him/her and tell him/her you can change, you really can! S/he'll see! It'll be different now!
Tell the world! Since nothing like that ever happened before (least of all to them), they'll be thrilled to hear about it. They'll be fascinated, I'm telling you. Really. They'll hang on your every word.
