BO from shirt and reapplying deo on stinky armpit. How do I fix this?

I've always been a sweaty person because of hyperhidrosis but I used to never smell but then this one time I wore a shirt that made me stank so bad and couldn't change soon enough because I was at school. That made me start to stink whenever I sweat, but it was somehow controllable as I only stank whenever I sweat too much. But then I started reapplying antiperspirant deo over already stinky armpit( I didn't know you're not suppose to put it on unclean armpits) from then on it became unmanageable. My Bo became so much worse like it can stink so far( maybe few meters or more not sure) I shower twice a day and my clothes are clean I use antibacterial soap and antiperspirant I've tried: antibacterial soap, betadine cleanser, benzoyl peroxide, mandelic acid, glycolic acid, alcohol, apple cider vinegar, charcoal tea tree soap, crystal deodorant, prbiotic deodorants, antiperspirant like mitchum arm and hammer and driclor(which made me stop sweating but made my bo so much worse?) and over 10 other brands of deodorant and antiperspirant. And the annoying thing is as soon as I put on my antiperspirant I start to smell bad already. If I dont wear one however, I start to stink so bad as soon as I sweat. I dont know what to do. I think Ive fucked up my microbiome so bad but I dont know how to fix it. Im thinking of trying ph balanced cleanser and ph balance clinical deodorant and benzac microbiome equalizer but Im not so sure yet because their qyite expensive here Do you guys have any idea how else I can try to fix this?
