Reddit, I need somewhere to turn to.

My girlfriend of the past year has been depressed for a long time and has talked about suicide in the past. She sees a psychiatrist for her depression, but she says it does absolutely nothing. I told her today while we were in bed that I wanted to go get some tomato soup, but didn't want to get out of my comfy bed. She turns and says, "I wish I had the same interest in life as you". I asked her then, "What do you mean, what is my interest in life?" She answered, "One."

At this point I asked her why she didn't have any interest in life. She told me she just felt this way, and that she sees being dead as being perfect. She doesn't want to be alive. She says being alive comprises of being sad, hurt and uncomfortable. I tried to tell her that happiness, joy and comfort were also a part of life. She answered that it didn't balance the bad at all.

She wishes she was dead, and I don't know what to tell her. I love her indescribably - let's leave it at that. I want her to experience joy and happiness, and I wish I knew what to do for her. I ask, but she just says it's impossible. That she doesn't truly have fun with anybody.

TL;DR

Fuck..
