Breathe. Just because one relationship didn't work out doesn't mean all of them won't. And it was nobodies fault. At least you tried and made yourself vulnerable, you did better than many. You were in the arena, be proud. Keep at it.
Breathe. You're going to do well out there.
Breathe. You're not going to let everyone down.
Breathe. You're not a fraud. You have some things to deal with. It's tough work but you can handle it.
Breathe. In 9 months you're about to be reborn.
