Pay attention in school, and pay attention to your friends, you're going to fall in love, she is going to leave, you will hurt for at least two years, but you'll be better for it. Its not the end of the world, its barely the beginning of your life

 Things still aren't brilliant, but they're getting there. The two suicide attempts weren't worse it and they made you feel worse.

 He is not the only fish in the ocean

 Don't change. What the world calls maturity is actually bitterness. Keep your passions blazing like the heat of 1000 suns.

 Would you be proud?

 Don't change anything! Not your mind, not your plans, not your dreams, not anything! Just keep doing what you're doing and remember that everything usually turns out better than expected! PS. Go eat some ice-cream now!

 Don't try to help your schizophrenic mum. You're now too depressed to eat and you're in a hospital.

 Don't do it. And stop crying, things will be fine.
