<human>: Can you summarize the given text in a few sentences?

The girl I love recently ended things with me. She said the spark between us is 100% gone and feels nothing when she talks to me. I don't feel the same way at all. She's the girl of my dreams, and I somehow got the idea in my head that we would never breakup, or at least i wanted to think that. Whenever i feel sad, she usually makes me feel better. Now when i see her name, I feel like shit and my insides  feel like they're melting. It's been three days and I havn't done much of anything but sulk and feel sorry for myself. I want to man up and feel better but anything I do reminds me of her and just makes me depressed and want to sleep.
<bot>: I made the mistake of falling in love with a girl. What  do you do to make yourself not feel like shit?
