1. I tried. I failed. But I tried. How many of you have? Everyone is an expert as they say.
Probably a lot of us, at one point or another. But we are not so self indulgent as to assume we are naturally gifted storytellers who don't need to research the mechanics, practice constantly, or take constructive criticism with good grace when asking for it. 
2. I stated I was not going to write anymore to shut people up as there is only so much shit a very timid first time writer can take.
Ppl making constructively critical comments are not 'shit'. Why don't you take some classes (online) and read the genre extensively? You seem fixated on thinking you can write, without changing things or researching when the vast majority have said your opening was unappealing, for various reasons. (Sorry)
3. I have no idea why a piece of awful writing could get anyone's back up. Nor why if I had thought it brilliant and now realised how shit is was might get anyone's back up.
The writing isn't what got ppls back up. It was the attitude that you already know you can write, and are not taking ppls freely given advice on board. You are being very dismissive.
4. It's my writing and I asked one question. People then decided they were all editors. That's cool. I don't give a shit. As I said, everyone is an expert. But I certainly reserve the right to say 'blah, thanks for the feedback, I'm crap, blah thanks'. There is no need to stick the fucking boot in. This is not AIBU.
You asked, ppl answered and tried to give advice. I don't see anyone sticking the boot in. Until you started getting arsey, that is. If you ask for advice and ignore it, then belittle those ppl (everyone decides their an editor, etc), they're not going to respond kindly, are they?
I hope you do find the motivation to take a class. You might enjoy it, and I'm sure it will help with structure and flow. You have a decent idea, but obviously need a bit of work and knowledge to flesh it out in a more captivating way.
They say everyone has at least one book inside them, this could be yours!
