are there writers here?

If you write, you're a writer. The only way to get better is to write more. I mean, sure, reading what other writers have to say about their process for writing can be useful. Analyzing works you admire to see what the writer did is important. But in the end, you have to put those techniques into use in your own work and figure out what you need to do to get the effect you want.

Also remember that every writer hates their own writing at least some of the time. Writers are more prone to imposter syndrome that pretty much anyone else. It's OK.

And keep in mind that the heart of writing is rewriting. Don't over analyze your first drafts — just write and get it down. Then go back through and figure out what you need to in order to make it work. Then do it again. And again, until it reaches a point where you're willing to let it go. It won't be finished — writers never finish their work, they just abandon it.

Don't be shy about sharing your work with people whose opinions you trust. Having beta readers — or literary guinea pigs, as I prefer to call them — is essential, and they need to give you feedback better than "It's good I like it." Being part of a writing group can be helpful because you'll be dealing with other writers who are going through the same things you are.

Also, don't take constructive criticism personally and don't be defensive. Constructive criticism is not an attack on you or your writing — it's feedback that you should consider. You don't have to accept it. You may disagree with someone else's feedback about your work. But think about it. Don't just dismiss it out of hand.

And, again, keep writing.
