Feel like im loosing my mind

I've got my results appointment on Friday i had biopsies taken from two lumps found after my yearly routine mamogram it was a massive shock to say the least 

By Friday it will be three weeks since my biopsies and I feel like im loosing my mind waiting for my results appointment the first week I just felt really sad and kept bursting in to tears last week I was on annual holiday and felt ok went back to work yesterday and the shit really hit the fan for me I just felt so angry, everything and everyone was annoying me, my husband had some lovely family news and was rightly in a good mood which for some reason ground my gears so much I lost it with him his chirpiness just made me see red 

I feel like im falling apart and im loosing my mind I've only got two more days to work until my results but I dont know how im going to get through it I cant call in sick so I have to drag myself in if I cant even cope now What am I going to do if the results are bad just feel like crawling in to a corner and hiding
