How to want to stop?

Hello! I am 18 years old and have been dreaming for 6 years. I want to stop or at least reduce my dreams because I feel like it wastes so much time and energy in my day. Sometimes I finish the day wondering where all the time went, and that I got nothing done. Often I put important things in my life aside so I have more time to dream, and sometimes it even gets in the way of my real-life relationships. There was a point where the dreaming got better but now I am spending more time in my dreams again. While I wish to reduce my dreaming so I can focus on my real life, at the same time I really don't want to stop. I feel so silly saying this, but I have spent years on the same characters in my head and have developed such specific plotlines that I feel  when I think about letting go. It makes me feel lonely and empty since I spent so much time invested in them. I have the urge to dream every day or else I'll feel anxious. I have tried several methods to reduce dreaming, and while they work for a little bit, I always just want to dream again really badly and I just dont want to let go of what I have created. I know I want live a fuller, more present life by reducing my dreaming, but I really, really don't want to let go. Does anyone else feel this way? Wanting to stop dreaming but fearing the feeling of letting go of them? Does anyone have any advice on how to overcome this? Thank you
