I don't think you're the only person who is writing how-too's, or helping others out, but I'm sorry you're having a bad time and feel like that. In a small community like this one seems to be, it can be hard to have an overlap between you asking for help on something and a person with that skill-set seeing your question. It's unfortunate, but there it is.
I understand your perspective, I've been there myself. All I can advise is patience when you're looking for help on something. Here's an example of a problem I had and could not find a solution for. I was at my wits end and feeling frustrated, and then someone came to my rescue much later.
All you can really do is try to report information and what you've tried, then hope someone's able to see it and has some insights. Then probably name your first born after them when they do.. cough wait, maybe not (Still many <3's to KakCAT). Joking aside though, sometimes things don't line up and that sucks, but there's not much you can do other than to keep at it, try other things, and/or go in another direction.
Regarding those contributions you have made, I'm sure there are many who have found value in it and appreciate it. I've made several tutorials in the past but sometimes it can be hard to properly articulate what you want to say. Here's an example...
I started out intending to turn this into a tutorial video on how to write MVC code and test it, but upon trying I got super bogged down in how long it was taking and in the end, just dumped a link to some code. Maybe I'll revisit it, but I just couldn't find the right way to express it.
That you can do so is great, keep it up! I think that's awesome! Maybe just don't think too unkindly of those who don't have your same ability to do that.
Anyway, as I said, it kinda sounds like you're having a bad time. Hang in there and hopefully things look better tomorrow. They usually tend to do so
