Pick yourself up off the ground and find another quiet place to cry. The crying isn't the problem; it's the people who see you.
Bury yourself old novels.
Go to therapy and order coffee afterwards, But always go through the drive-thru. You can't let them see you fully.
Take your medicine instead of stockpiling pills like a suicidal squirrel. Attempts won't get you anywhere, you know you're too afraid to die.
Make some friends and fall in love with all of them. Know that they will never love you back but do it anyways. If someone tells you you mean something, they're lying. That's what happens when you're sad. People pity you. The last thing you need is pity.
