It's like this. If I was in love and someone was in love with me, I'd probably have a lot more will to live. It's hard to want to off yourself when your brain is full of feel-good chemicals and you have a sense of purpose and responsibility related to another person's wellbeing and happiness.
Here's the thing. A couple things. 1) I have totally given up on searching for love, I am so apathetic about life and worn out that it simply isn't a priority anymore, 2) I am not living my life in a way that would be likely to attract a mate (I am out of shape, not financially independent, oh, and I hardly ever leave my bedroom). Also, I guess 3) I am to an age in life where I feel pretty discontent with basing my happiness and will to live on a relationship. I've seen a whole lot of relationships end. It's just a non-sustainable way to function.
For me at this point, I feel like the only way forward is to find a will to live that comes from within. Or kill myself, whatever.
