Thrush

I have bad thrush.
I've had this for about over a week now but I feel like I've had it longer as my symptoms have worsened very quickly. My boyfriend and myself had sex about two weeks ago,before I knew I had thrush and he caught it too from me but now his is cleared up 
without using any cream..(We haven't had sex since I found out I had thrush).
Between the lips of my vagina it is cracked and red. It really stings and itches😩. I also have it in my anal too I can't help but feel depressed and I also feel anxiety too, I can't sleep I'm awake most of the night with the itching and I can't even lye in certain positions that help me sleep..
I went to the doctor only two days ago and was prescribed to flucol (150mg) I've taken the first tablet and still no help! 
I've now taken the second tablet today and I'm praying to God that it will work😔.
Sorry for this being so long, but any ladies have advice? It would be gratefully appreciated!🌸x
