here too, sorry for the late reply T_T RS didn't notify me :(((

I am sending you huggies anon!! I have the opposite usually, so idk if I can give any good advice but I'll try!
maybe you can skip reading it back or ask a friend to beta read it so you don't get that feeling that you want to delete?
Or maybe you can practice your writing with some drabbles until you feel a bit more confident and happy with your writing?
Either way, I can tell you that it's okay to not be perfect!!! As the writer, you always notice the flaws the most, and many readers won't even notice anything! Many readers are already happy to have something to read, and if you enjoy the process of writing then in my opinion you've already succeeded :D

good luck sweet anon!! I'm cheering you on!!
