Sometimes I Want to Quit Writing.

I try and try to write, but i continuously get stuck in the process. Maybe a few sentences to a few paragraphs before i just have to go back and edit what i already have and then im stuck again. Then the process repeats. Once i have something complete i go through the 'should i edit and post' phase. It be like,

Is it good enough to post?

What if no one likes it?

Is this the best i can do?

Should i rewrite and compare the two?

Should i wait to reveal this part a little later?

Am i too dramatic with my writing?

Why is no one reading this?

What is the purpose of posting this?

Will i get any new subscribers, recs or comments?

After asking myself all that and more at least 12 times I suck it up, take a deep breath and take my chances. I post then i want to read, but i don't.

When I read and write at the same time i compare their writing to mind; admittedly wanting to give up repeatedly.

Also i don't want to accidently plagiarize anyone. I wouldn't want anyone to do it to me. So i will read and comment after i post my next two chapters and take a break to research. So rec stories. Also, How do you get over your self doubt?

What do you go through when writing and the steps you take to get through it?
