This is true. I have my best-girl-friend, but I feel alone when I talk to her, because she says she understands, but I don't feel better. The ways that good guys comfort girls helps with the kinds of things that girls can't help each other out with.
Trust me, I know how it feels. I know exactly how it feels to cry in the shower so no one will hear you and waiting for everyone to fall asleep so you can fall apart. For everyting to hurt so bad you just want it all to end. I know exactly how it feels.
