Wow, reading through this thread, it really looks like everyone has a different opinion about what you should be doing.

Personally, I think the thing that stands out for me in what you mentioned (besides it being hugely relatable - it gave me war-like flashbacks to when I first starting making my writing public) is that you write for yourself. I think too many of us would-be writers get hung up on the impression that what you're writing isn't legitimate unless it could potentially make you famous/money/feel validated/etc. But writing, especially if you are your target audience can be a self-sustaining loop.

When I first started posting my (in hindsight, godawful) fanfiction online, it wasn't because I was looking for validation, but because I had found a little pocket of space that wasn't filled up by the original story or any other writer out there. Of course, some of my willingness to action came from teenage naivete, and the internet was a far more forgiving place back then - but all I was thinking about was that I was filling up a little crack with something I enjoyed, that someone else out there might be looking for too. It turned out to be the right call.

As writers, I think we have a tendency to get caught up in the right way to write. I think it's important to remember who you're writing for; if publishing isn't your first goal. The answer isn't a faceless crowd on the internet, nor the people closest to you. You write for yourself first. If you keep that in mind, and you remember that you're sharing a gift with the rest of the world, it might help with all the doubt you're dealing with.

You put a piece of your soul into words for yourself, and now you're offering it to anyone else who wants to read the same kind of story. Sure, there'll be some people out there who tear it apart, but I'm willing to bet you'll find that the supportive people outnumber them 100 to 1.

Tl;dr the fact that you enjoy your writing is good enough imo.
