Yeast Infection not going away. Else?

I used to have yeast infection yearly even when I was not sexually active. (Back in 2013-2018) . Since I recovered from typhoid last year (august-october 2019), my vagina doesn't stay healthy. It feels like yeast infection just need a very small reason to come back. Since February I am suffering from itch continuosly. And in March this is not going away at all. This month my vagina had too much discharge earlier it was very watery ( felt like periods flow) , them after few days it was very thick and white discharge and this week no discharge. It's very less now. Also I can see Yeast infection on urinary tract/ urinary opening and I feel burning like sensation. I tried dusting Powder, Vwash, vaginal creams and this time it's not working and still using these. I am scared. Is it something else? My heartbeats too usually stay very fast nowadays (108-120/per min) I also get rashes and infection just after my periods. Help me please. It's the first time that infection is not going away
