Embarrassing self hygiene

Okay before I begin I don’t really want comments telling me it’s nasty or ew or any of that because I know it is and that’s why I’m asking for help. I don’t know why my body is like this but I can’t seem to keep my

body clean. I shower once every day or two, (considering I didn’t do anything that got my dirty) and when I wipe I always wipe until it looks clean! Yet my vagina always smells, I get stains on my undies, and my armpits always get swollen lymph nodes on them! They hurt. I’m not close with my mom and self care was something kind of implied but I don’t know what I’m doing wrong. Any recommendations on products or things I can do differently? Thank you all so much. It’s embarrassing.
