AAA hello! Sorry I couldn't reply any sooner! I've been focusing a lot in other hobbies such as art and I've been trying to create my own webtoon!
Anyway, I just want you to know that you'll get there! I don't really have any tips or advice that could work in just a few days but all I can do is give you my support! You'll learn to get better; just keep believing in yourself and pursuing what you love or what makes you happy! All we can do is keep trying until we eventually get better.
Writing takes time and the best stories often take long to think of. Don't pressure yourself into writing more often than usual, it gets tiring. Don't forget to take breaks! From experience, the best way to write a story is to try to incorporate some kind of self experience or memory.
I hope you're having a wonderful day and that you're doing okay! Stay safe and keep writing! :>>
