So here's a first post from me. Woo frickin hoo.
A little background on myself. 16 years old, american high schooler. Male. Been lucid dreaming about 6 months now, learned how to do it from the internet.
Here's a bit of a problem I'm having.
A month ago my first girlfriend broke up with me, fairly roughly too. We were together for a year and a half, and I loved her deeply. Two weeks after she dumped me, I started dreaming about the last time we were together. It always goes the same. It starts out with us together at the park down the street from our school where I first asked her out. We're having lunch, and she's being distant. We have the exact same conversation as we did in real life, always exactly the same. Then we get up and suddenly we're standing outside the door of our school where she dumped me. We have the exact same conversation as we did in real life, you get the picture. They're my memories replaying. I've had this dream consistently every night for weeks, and it's always the same. The worst part is that I have no control. Before this started happening I was pretty good at dream control. I could change my environment, fly, do all the cool lucid things. I haven't been able to change anything in this dream. I can't even control my own actions, other than being aware that I'm dreaming. I've tried all the methods for getting out of nightmares. Closing my eyes and imagining a nicer dream, telling myself it's going to change, concentrating on making it stop. None of it works, short of waking up. I'm in a depression, it's killing me. Every night I relive such a painful memory, and always wake up sweating on the verge of tears. Maybe I'm just not skilled enough to change things? I'm on the edge of looking online for a way to sleep without dreaming. I don't even want to sleep anymore.

Any of you more experienced dreamers think you can help me?
