I don’t mean to be rude but I think it would be easier for you to do long one shot stories so you don’t feel pressured to upload chapters and have a certain schedule, but if you want to add on to the ones shot you can .
I think you have a lot of prompt and ideas but you can’t write about them because you don’t want to put out more unfinished stories.
With the long stories I feel your expectations are high for writing which put more pressure on you then causes you to have writer’s block. That’s why I think it would be easier for you to write really long one shot or short stories so don’t feel pressured, just a suggestion and take care of yourself ☺️
