I want an end to my mal-adaptive day dreaming.

Im in a relationship and I'm constantly day dreaming about a better one. Im ignoring problems in my personal life by day dreaming about a more beautiful and "meaningful" life, even though the life I already live has the potential to be as meaningful as possible. Im constantly thinking about the past and "what ifs". I play out my day dreams constantly in my head at work.

Truth is, I'm scared. I'm anxious. I dont want to face the things that make me uncomfortable or anxious about my life. This day dream shit is a cope.

I'm aware of it. Now how the fuck do I end it?
