Wound care?

Used to be really bad at wound care, would just put tape over cuts 😭 it was bad and now that I've relapsed and probably won't stop for awhile I need advice !! Rn I'm just using those cheap bandaids that fall off every 5 seconds but I'm afraid of if I use to many of them my parents will notice :p I can totally go to the store to buy my own but I would need excuses to go and I don't have the energy to tbh. Any advice or other things I could use? Btw gauze isn't in the picture I can't use it cuz it gets my bracelets all sticky :')
