Am I the only one with such a wildly multi-grain beard? ...
No, I expect most of us have at least the odd problem patch. Like Vinny, I should go from Adam's apple to earlobe on my throat (not easy for the non ambidextrous straight razor user, by the way), but as Antdad says, N-S is a workable compromise. Maybe your growth patterns will settle down; at any rate you will become more familiar with them soon enough.
For starters, I suggest you avoid the Feather blades for now. They have a track record of causing irritation in some people, and when they're past their best, they're frightful. Red Personnas would be a far more forgiving choice; fortunately that's what most supermarket blades are.
Over and above the "no pressure" and "go easy on yourself" advice, I suggest you concentrate on good preparation and a suitable post shave routine. For the former, hot water and a coat of lather left on for a couple of minutes works for me, but I doubt that a hot towel ever did any harm; as regards the latter, thorough rinsing is rarely emphasised enough, I reckon. You want to be sure that there's no trace of soap left on your face whatsoever: warm rinse followed by a thorough drenching with cold is the prescription. I'm in Tony's camp as regards aftershave - high alcohol splash, the more sting the better - this seems to settle things down better than anything else. And finally: No faceturbation!
tl;dr? Good prep, one gentle pass with the grain (where possible), rinse very thoroughly, apply astringent, leave it alone. Matters should improve before long.
