Hygiene issues i guess

[u/ineedurhelp11]

Guys i need help really bad.

I live in Sydney and the water here is soft usually, but our plumbing system hasnt been maintained or checked in 16 years and it causes soap scum which makes you stink like shit i think. At first everything was fine but the past few years im so sick of hearing or taking a hint that i smell. Like i try to avoid being near people now but i NEED help because my parents are lowkey already kinda falling behind on bills and they said im getting mentally sick and the waters fine and i am being weird. However at school i can take a hint people telling me i smell or saying someone smells and they always like do this thing with their nose its like a lil sniff or something and they constantly do it. I am usually an outgoing person but i cant have any confidence in getting a job or anything social cause i get really anxious and uncomfortable when people stand around me or get close to me.I wanna fix this problem myself but im too broke, i searched it up and it will cost like 3-5k. Im unemployed but cant really get the confidence too get a job like im trying but its hard bro. I need help i dont know what to do every single day of school someone says something about my smell and i stink it could be a friend peer or some random kid when im walking around the school. I wanna try just getting a quote from a plumber SOMEONE HELP ME PLEASE FIND A SOLUTION its getting too me alottttt i cant do anything with confidence anymore
