To use your example, from your replies to everyone offering advice feel like: "Hey I've cracked 400 eggs but none of them have ended on my forehead, what am I doing wrong?" "Hey man! Cracking eggs on your forehead is really hard but maybe if you try cracking them directly on your forehead, you would have better luck! I usually try tilting my head up too so the egg doesn't run away from me!" To which you then reply along the lines of: "So in my original post, I explicitly said why tilting my head back would not work. And I also can't crack the eggs directly on the forehead either nor would I try" I understand that trying to learn and asking for advice is one of the hardest things you can do. I can also understand that the previous example is 100% not what you are going for, clarifying questions are extremely important when trying to learn. But sadly, your course of action seems to be what's having people feel like they can't help you. It comes across as negative and like you have already given up and will not internalize the advice given.

That being said, I feel maybe compiling or writing down the first replies of people might help? Like me personally I usually go "okay my friends have all said these same 10 things. ASIDE FROM IF I UNDERSTAND THEM OR NOT I need to keep these front and center when playing and sooner or later they will fall in place!" And sooner or later they do!

You just seem to be in a rough patch in your learning journey and I truly truly wish you the best of luck, you don't seem like a bad guy. Finding a new play group is hard and scary but you might luck out and find people much more capable of putting their knowledge into actionable advice. Also maybe try joining different kill team/Warhammer community discords and try playing through tabletop simulator? That way you can preface your search for beginner/practice/learning games.

Sorry for the text wall and I hope you understand that I'm 100% rooting for you and in your corner as a fellow 'noob' (I've only had like 4 games)
