Potential Vaginal Yeast Infection, Herpes, or something else,

I just had my son about seven months ago. I found out about three weeks ago that I was pregnant again. I ended up miscarrying a week later. Last week, both my children, my husband, and I had scratchy throat, cough, and overall feeling unwell - Flu, COVID, and RSV all came back negative. I was prescribed a Z pak by my primary physician, which usually always leads to a yeast infection, so she also prescribed me Diflucan. Two days after taking the antibiotic, the itching started severely. The first dose of diflucan did not cure the infection so I took another. It seemed to help but I still felt "off" in my vagina area (slightly itchy, sore). Two days ago, I started feeling extra sore and then noticed a bump on my labia. Its not oozing, resembles a pimple, and feels like a pimple under the skin on your face. I have a LOT of thick white discharge consistently. I did a phone conference with a doctor on my app and he had me convinced its herpes. I plan to see my primary care doctor but i'm scared. Ive been with the same partner for over two years. I also suffer from anxiety/depression and this has taken a toll on me. Thank you in advance for opinion
