Depression or Heartbreak?

It is unhealthy to obsess over someone that much, in my opinion. Putting too much value on one person when you're not even in a relationship with them is setting yourself up for failure. What I think you should do is express to her how you feel, see what she says, and go from there. Take the risk, and learn from the outcome. There are PLENTY of women, and you will stumble upon the right one, whether now or later on in life. However for the now - If you don't do anything, your situation will stay the same. It is you who put yourself in the friend-zone, and it is you that has to get yourself out by "manning up" and taking the risk. How can you be heartbroken if she hasn't left you? If you are depressed, it is your mind's way of trying to tell you that you're holding yourself back from taking a risk (in your situation), and you're hurting yourself in the process. Remember, if you want to find the right one, you need to realize that you need to have more than one reason TO love them. It can't just be infatuation, nor can it be just love, nor can it be just shared interests. It has to be a combination of multiple qualities that produce a lasting relationship.

I know we don't go out. But it's like we do, we always tell each other that we love each other we hold hands walking down the hallway..We do everything a normal couple would do. But she also loves this other girl. & No I may not sound right to you, but it feels like.

@LocoLatte:) This just sounds weird... It is like "Look but don't touch". Or "Taste but don't swallow". Again, look at your situation right now. What is this relationship currently giving you? Pain, Depression, Sadness, Tears. Nothing good.

You two are not in relationship. You just said you cry and "I rather die than to live life without her". I don't want to sound like douche but this is messed up. You seriously need to realistically look at your current life and see how much nerves and time is this girl costing you. You just have to learn how to deal with at and go with "no-contact" rule. You will be heartbroken in life many times. If you can't cope alone, go to therapy, because right now you don't sound very healthy. Cut all contact with this girl, cope with it for a month or so and you will be fine.
