recurring yeast infection

okay so a month and a half ago I noticed a god awful yeast infection, my Dr prescribed me the pill (can't remember name) it didn't work. I bought monistat 7 day treatment, it didn't work. I called Dr, she prescribed me 2 pills so a double dose. It didn't work, here I am now. I can't explain the emotional and physical toll this is taking on me. I'm getting depressed, who wants to live a life where every day that are uncomfortable. I'm calling Dr tomorrow and gonna go in. seriously though, what else can she possibly do for me. WTF is wrong with me... I don't wear underwear, I change my pants daily. I shower two times a day, I do not scrub or use soap on my vagina. Anyone know what this could be? Seriously getting f***in depressed, idk when I can even go to the DR because I'm a SAHM and have no one to watch my baby, plus he is super fussy so idk who I trust either. Uhg.

UPDATE: Thanks for replying ladies, I sincerely appreciate every comment, I have HPV and had a Leep procedure 6 months ago. I did a pap 2 months ago and my Dr told me I had a yeast infection. She told me my PH wasn't off, I almost wish it was an STD tbh because then it could be curable lol.
