I need writing tips asap

I stopped reading actual books in so long that I think I lost all my writing skills and my pride won't allow that.

I have a chance of being invited to a writing group for horror romance (underrated combo) and I can not mess this up.

I need anything, how to expand sentences, how to describe the 5 senses, characterization, YouTube tutorials, anything.

Please help this non novel and book reading user it is not my fault that one day I decided I'd just read manga/whas/huas for the past years, and never tried writing after that.
