I prefer Syntax Matt and bert squabbling instead of this shit

I mean this in a nice way, but Google is your best shot at nailing down the basics like this. I found this straightforward and expansive image just moments ago, in fact. I'd just give you a well-meaning but probably flawed explanation.

Beyond stuff like this picture, the only real way to get the particles is to study and practise a lot. Read sentences in Japanese and listen to Japanese being spoken. Get a pen pal or someting, if you can.

Hello Talk, I think, is an app made especially for language exchange and practise, where native Japanese speakers can correct your grammar (hopefully in exchange for you helping people learning English). You might give that a try, once you're more confident. Would be a good way to spot if you're making any mistakes.

I'm not really very good at Japanese, by the way, so you probably shouldn't rely on me for advice anyway. You could probably surpass me handily with enough study!

Then again, maybe I should play it up a little, if it irritates certain fora posters. ?
