Your English is understandable, but still recognizable as written by someone who's learning. Your next major challenges will likely be a) learning tenses other than the present tense; b) understanding what prepositions to use in what context; and c) understanding where to use singular vs plural nouns.
You shouldn't feel bad about not having internalized those points yet. The present tense is always the first tense a language learner encounters. And even as a native speaker I'd be hard-pressed to articulate clear rules for B and C. IMO the best way to learn those things is to read a lot that you're confident has been written or copy-edited by native speakers. For instance, articles in the NY Times or the New Yorker are edited to meet a high grammatical standard.
Are you looking for direct feedback on your writing? Here's how a native speaker would write the first paragraph of the linked article:
Writing has been one of my hobbies since I was in high school. But writing an English story is still a bit new to me. I started writing English articles/stories a year ago.
Another way to phrase that last sentence might be:
I've been writing articles and stories in English for a year now.
Or:
I wrote my first English article/story a year ago.
