Please help

Around 7 months ago I took some tablets for a skin infection. From that I've had thrush. 7 MONTHS. I honestly think I'm going insane now ! I was first given by my doctor a pessary(didn't work) since then I've been so stressed out, I haven't had time to go back. So last week I went to see the doctor for the second time and she gave me a 3 day pessary(finished the last one Saturday night) and now I fear it's not gone as the symptoms have returned. I really feel as though I'm going to break down, I just want it gone. Any suggestions ? 💜
