Don't be nice to him. He's delusional and will think that means you're dating. I know you want to see the good in everyone, but seriously, ignore the guilt you feel. It would have been better to feel guilty and avoid the stalking.

 Fight back, scream, kick, rage. You'll be on your own for a long, long time. Then you will find the love of your life and things will turn out OK.

 Have faith in yourself, you're good enough. Follow your dreams and one day they'll come true.

 Quit pretending to like that weird music.

 Know that you can't fix everything. And that is okay.

 Do whatever the fuck you want.

 Do not hurt the one you love. It only takes a few seconds to break someone's heart, but it takes years to mend it.

 It's not worth it to throw your life away to buy pretty things.
