Lena Dunham is nothing if not honest and open. In conjunction with the Sept. 30th release of her book "Not That Kind of Girl," the Golden Globe winner offers up advice based on her own experiences with a negative body image, bad sex and unhealthy relationships.

A self-proclaimed "plus-size college student" named Megan writes in about finding her confidence amid feeling unattractive. She tells the "Girls" star that she's nearly 21 and has still not been in a relationship due to her feelings of low self-worth.

Having felt like this herself, Dunham tells Megan, "I went through all of college, dressing like a lunatic, wearing neon ...and secretly hating myself."

"For me, confidence comes from feeling happy with my habits. Feeling like I can be proud of my life," she advises. "I know that I am the best version of myself that I can be, and that doesn't mean losing 30 pounds. That means taking care of myself and treating myself like precious cargo."

Sort of whispering, Dunham adds, "And also, I will say, I've been a bunch of different weights, and being temporarily 135 pounds, I was so obsessed with food. I was so into counting almonds that I don't think I got laid that entire time."
