Please help as I’m so scared

Hello, I noticed a red blemish on my breast on Sunday morning and for some reason I googled it. Inflammatory breast cancer Kept coming up. I went to my doctor on Monday and was prescribed antibiotics as he thought it could be an infection. I've been taking the antibiotics for 3 days now and the symptoms are worse. Clearly they antibiotics aren't working. My blemish now has purple bruising around it and the rest of my breast and my lymph nodes are still swollen and have become more painful. I am absolutely petrified that it's IBC and have made a private appointment for next Tuesday. All of my  symptoms are exactly the same as those for inflammatory breast cancer. Has anyone else experienced similar symptoms? I've cried for 3 days , can't eat or function. I'm totally consumed by it. I'd really appreciate your response. Thank you, laura x 

I am 41 BTW
