The definition of a writer's block on Merriam Webster is "the problem of not being able to think of something to write about or not being able to finish writing a story, poem, etc."
Writer's block is something that I do not get often, but when I do, boy, it's a problem. And, dear reader, I am currently going through one, so that's an issue.
I either don't know what to write about and literally go through millions of ideas in my mind that do not sound as appealing/interesting as they should, or I start writing something I'm interested in or have a lot to say about and then -- bam -- it all goes away and then I can't think of anything. It's honestly such a frustrating thing, and you have absolutely no control over it.
I know many people on Wattpad, an awesome website (and app) that has millions of stories written by great, creative people, that go through many writer's blocks that eventually lead them to a short or an eternal hiatus.
I also know many people who even in college go through writer's block -- whether it's for their creative writing class, for an essay, or even while writing a research paper. Those are the worst. Those are the ones that involve tears and a lot of hair pulling, which can get even more frustrating if you don't have any hair to pull.
These are the five emotions that you tend to go through while having writer's block:
1. Misery
2. A bit of self-hatred
3. Anger
4. Anxiety
5. A lot of frustration
Because in the end, you know that regardless you need to be able to have something written down and not end up like Spongebob.
So if you have writer's block, do what I did just now: walk around; listen to music, talk to someone, and then try to write something. You'll be able to get somewhere even if it's not where you want to be.
Good luck!
