Improve my writing skills✒

Hey, guys! My name is Sofia and I've been learning English for around 7 years now and while I feel like I'm quite good at speaking as people do understand what I say and it's not really hard for me to understand their speech as well.

However, I think that I lack on the writing part. My sentences feel heavy and unnatural (I guess?). So I would want to find some teacher, who could help me get better at writing. I've also picked up creative writing and now try to spend at least hour a week to complete some tasks that I create for myself. I want to feel better about what I do and more confident as well.
