Hello, I need help

I can't say for sure that you have MD, but it certainly sounds like it. You saying "constantly make up scenarios, stories and situations in my head..." would lead me to say that MD is at least a component.

That statement certainly is what I do... I painted one of my rooms yesterday and the entire time I had a scenario going on in my head. I can recall painting my room but I remember the conversations I had in my head more vividly. Painting a room, for me, is a pretty mundane task so it takes very little to drift off. But, I try to do things that are more constructive when I want to pull myself out of my head. I'll do things like baking or cooking as it keeps my mind on the recipe and the "building" process of the food. Same with my job. I am in a creative in marketing so I have projects that keep me from drifting.

Sometimes I do have a hard time starting a project if I'm in the middle of something in my head, but I'll force myself to start the first task then it pulls me out and then my focus is on the project. If I didn't have that kind of work, I think doing something creative like drawing, painting, writing poetry, taking up a musical instrument, learning a language, etc., would probably help to keep me in the physical world. Also, since this pandemic started, I'll get lost in my head easier so I've been watching a little more TV than I used to. I generally don't care for TV as I'd rather do other things, but since I don't spend much time with fam and friends now, a TV show will keep me out of my head for the hour or so that I'll watch.

It's hard to avoid mundane things... laundry, mowing the lawn, washing dishes, painting a room, etc., but trying to find things that keep your mind focused may help. I can't say that this might help you but these are things that I've been doing to help manage it. I'm still working on it as there are times that I'll "go away" for hours on end without even realizing it. But I'm now much more aware of things I can do to help.

As for who to talk to, that I'm what would be best for you. But, personally, I think starting with a counselor is a good idea. I saw one two years ago for something that I was going through. It was WAY more helpful that I thought it would be. What I was going through wasn't fixed instantly, but talking about it and learning about things to help manage my way through it helped very much. I may go back to my counselor for this (we never talked about daydreams as I really didn't think it was an issue at the time) and see what they think, but I've not settled on that decision yet for myself.

Sorry for the long reply. I hope you find what works for you!
