The best writers stand out. Others wouldn't do what you are doing because only
you can tell your story. You are unique, and by the sounds of it, so's your writing, and that's awesome! That's what writing is about - finding your own voice, telling your own story, forging your own path.
Maybe you could stick a wee message to yourself on your laptop or notepad? I have quotes - both from the internet and hand-written - all over my desk, reminding me to work hard, to believe in myself, to focus on the process and not the goal. Sometimes (okay, not all the time) it really helps. Maybe spend time reading interviews by your favourite authors, and pick out quotes that reveal their own self-doubts and insecurities. A little reminder that Author X has the same worries might help when you're feeling a bit rubbish.
I also compare myself to others all the time; not so much writing style, but productivity. I believe all published authors live and breathe their books every second they're awake (and sometimes asleep) and I feel bad because I don't. I worry I'm not committed enough, that I spend too much time daydreaming; I worry about the days when I do not want to write at all, when I'd rather work on the bathroom mould than my story.
Writing is such a tough and lonely job, and you have to work so hard before you can produce something that might bring external praise. I find it almost impossible to believe there's a single writer on the planet who doesn't doubt and compare and worry from time to time.
Stick at it! Your individuality is what makes you special.
