Oh, dear @gertu, YOU ARE A WRITER!
Even if nobody else reads your words, or if other critique and judge your words until you never want to write again, know this: you write. You are a writer. I'm so sorry others have detracted you from that!

You:

What I write is what I do because I feel it, and I want to let it out.

Keep doing that! You can call it journaling or blogging. It's therapeutic. It's good for your own well being, and it could be good for whoever reads your words in the future (family? grandchildren). Even if nobody but you reads it: you are doing a great thing here. Keep writing whatever YOU want to write.
What should I do to write something that others like, and at the same time, is that something that wants to come out of my mind and my imagination?

I don't know, maybe I keep receiving messages from knowledgeable people who want to keep teaching me how to write for others. I wonder again: Is this way of growth for me, is it to my liking? Do I really want to write for everyone to like me? Or do I want to keep writing my imaginary fantasies? My life experiences or topics like that.

If your goal is not to be a published writer whose writing sells well, then pay no attention to what sells. The market is of no concern to you if you're not seeking to market your own writing.

Even if your goal was to publish, guess what famous writers would advise:
WRITE WHAT YOU WOULD LIKE TO READ.
Write for yourself.

Says the foolish woman who never takes her own advice...
I wrote what I liked to read and it got shredded in a fiction workshop by people who beat each other up with "Writing Rules" such as "Don't use the was + -ing construction," e.g., don't say,
She was standing there.
Write,
She stood there.

Then there were the POV (Point of View) police,
and No Omni! (no omniscient narrator),
And
Write in first person, present tense!

Meh.
Ten or twenty years since then, guess what's back in style: the omni narrator!
Third person narration!

Again I say, YOU ARE A WRITER, even if nobody else reads your words.
Writing is therapy.
Writing is good for YOU.

Keep writing!!
