a nasty situation

I'm a pretty clean girl and i take at least two showers a day using mostly hot water . For the past 3 or so weeks ive had what i think is a yeast infection but i dont like going to the doctor for these type of things nor do ik which one i should go to . Is there any thing i can take or do better at home to end this 😓 i'm beginning to feel gross and stressed because of it . Im highly ashamed of myself .
