Waiting

Hi I went to the doctors this week after discovering a few breast cancer symptoms and the doctors found a few lumps and other symptoms they were concerned about and so have made a referral for an emergency appointment for a ultrasound to be investigated futher. 

I haven't been diagnosed yet so unsure if it's okay to post in here, I hope I don't upset any one by doing so but I'm just so losted and scared and don't have anyone to talk to about my fears with and was hoping that someone here would be able to guide me threw next steps of what to exspect and advise me on what I should do next.

Doctor said it'll be roughly 2-3 weeks until I recieve letter from NHS in post with appointment but I have no idea what to exspect from appointment (breadt ultrasound since I am 32) and I am scared. 

I feel so caught in limbo, I am in pain, stressed about future and unsure what to tell my daughter and family, I don't want to tell them until recieve trst results so I know for definitely if it is cancer but what do I say to explain my fatigue, stress and symptoms for next few weeks whilst I am waiting on tests? 

Just feel so frustrated caught in a waiting game and exspected to carry on as normal for weeks before I get tested but can't help worrying and thinking about worse case it is cancer and thinking about leaving my daughter with out a mum, that terrifies me. 

Symptom wise I have pain in breasts, a large lump in left breast, changes to nipple and 'orange peel' that the doctor was concerned about as well as sever fatigue, any advice on how to manage symptoms as I was told to take paracetamol in meantime which isn't helping at all.

I just feel angry and let down, told doctors are concerned and need an emergency appointment as could be cancer but sent away with no info on next steps, what to exspect, no real help in how to manage symptoms and no advice on what I should tell my daughter who is 7 in meantime who has noticed I am really tired and I need to tell to hug mummy gently, not to climb on me or that I can't play rugby with her/ play certain games with her because I am in pain but unsure if I should tell her my breasts hurt and why they might so can not make a big deal about it so its not a shock / so scary later if I am diagnosed or if I should not give specifics about where pain is despite her asking where I hurt and why?
