Is my cousin faking cutting/depression?

[Frank]

People cut because it is the only way they know to deal with their emotions.

Four marriages is a good sign that the mother is not capable of forming a healthy relationship, so the daughter has nobody to turn to.

She turns to cutting. While many cutters do try to keep the cutting secret, some of them display them.

It's easy to write her off as an attention seeker. She's desperately reaching out to someone to connect with. That's what she really needs.
