I don’t think I can take much more

I know some people on here are so brave and I'm so weak. I haven't even been diagnosed yet, but I'm thinking the worst. I went to the docs who prescribed antibiotics but this made no change to my breasts. My nipple has suddenly inverted and I'm getting terrible achiness verging on pain in the nipple area. Today my breast felt so heavy and swollen and I'm thinking it's going to be inflammatory breast cancer. I took some ibuprofen and that helped. I've  had to ask my Gp for medication as my anxiety is through the roof and I can't eat or sleep. My appointment was meant to be the 28th, so four weeks from my Gp appt but I've booked a private appt for next week as I just can't take this anymore.
