Hey, luckily, your feelings of worthlessness do not make you worthless. It's normal to go through tough periods when you don't feel understood or appreciated. It happens as you grow and discover yourself more and more as you change more and more. But changing also means that you have to redefine the way you connect to the world around you and that makes it hard.

Sometimes it helps playing with your cards on the table - try telling your friend how you feel when she's being that way to you. But be prepared that it might not help. People have different understandings of how they should communicate and how personal a conversation should be.

Good luck!
