First of all, you can write. You love writing? You're a writer, welcome to the club. Never put your words down, at least not seriously. You are good at writing and you're getting better. It's not a case of you not being able to do it because we've been forced to write ever since we were four/five/six years old and we'll continue writing.
To get better, practice. That's literally all you can do. Nobody can help you because only you can help yourself. If you're passionate about writing then research! Find things to write about. Write about the sky being greyer than a metal or the dull glass of a coffee table. You can write about anything!!
If you're trying your best then you're at your best. And your best is only going to get better
Hope I helped
