Biopsies thinking the worst

Hi,

I'm new, just joined. Mother to three children. Yesterday I had an appointment at breast clinic. I had mamograms and ultrasound. Found a suspicious lump in my armpit and breast. I ended up having three biopsies. I was told they didn't like the look of it and the doctor booked me in for a lump removal on 13th Friday the day after biopsy results. Since then I've been worried sick. I have the occasional cry. I can't seem to eat cos worrying. I can't sleep. I'm just living in dread. Anyone got any advice how to deal with it?
