Cough Medicine, Writer's Block, and A Silver Lining

So, it's one am my time, I'm doped up on cough medicine, and I can't sleep.

My Current State of Confusion...

I can't stop thinking about writing.

I guess I've never questioned myself this much before.

The theme for my new manuscript keeps changing, and I can't figure out who my characters are anymore, or who they're supposed to be. It's like questioning my own identity.

Where do I go from here? Do I just pick up the pieces and move on, am I experiencing writer's block or side effects from this cough medicine?

And should I be querying my other manuscript while I'm writing? What do I do at a time like this besides wait?

I feel like I'm always waiting--waiting on words, waiting on feedback, waiting on agents, waiting for this commercial to end....

And I can't stop thinking about that movie I just watched (for like the millionth time,) A Silver Lining's Playbook. If you like crazy people, love stories, football, and writing, this movie is for you, hands down.

Well anyway, one of the main characters, Tiffany, goes off on one of her crazy moments...inserts gif...

And sometimes I feel that way after I write, like somehow my own words are betraying me by not giving me anything else to say . . . like they're judging me. It seems irreversible.

It's like, how the heck am I supposed to finish this chapter if my brain doesn't work the way I want it to?

Why are my main characters so complicated, and why is the word excelsior still stuck in my head?

And now, I'm going wayy too deep. I think that night time medicine is setting in.

On a more serious note, does anyone have any advice about writer's block? Is this normal, the way I feel?
And seriously, check out this movie, or even the book, it's my favorite.

Till next time, ya'll!

Happy Writing Days!
