Waiting for my breast clinic appointment

Hi,

I’ve just joined this forum after spending far too much time scrolling through Dr Google! I know it’s absolutely the wrong thing to do, but I can’t seem to help myself. It’s a mixture of wanting to feel informed of what to expect (whatever the results) and looking for reassurance that it’s nothing to be concerned about. 
I had a bright red patch (3-4 cm) on my breast last Monday, no lump or anything so I presumed I’d leant on something or knocked into something without realising. The next day it was still bright red but there was a small hard lump there. The redness faded over a few days leaving just the lump. I was on a school residential at the time so had a video gp appointment mainly for reassurance and to see if I could start the process of a referral if needed. Needless to say, the appointment had opposite effect. 
The doctor said I really needed to return home straight away (I was due to return home with the children the next evening). She was concerned that I’d waited 2 days before getting in touch. Since then I’ve had several phone calls which in part is due to going private so it’s doubled up the contact as the NHS have also called a couple of times. All of this has sent me into a tailspin and although I only have to wait for a week for my one stop appointment (2 weeks after noticing) it feels so far away. I know this sounds dramatic as I appreciate that I’m lucky for having a relatively short wait. It’s like an ear-worm constantly present whatever I’m doing. 
The lump feels hard and like the end of my finger deep within the breast tissue, so only small. although last night it felt a bit bigger along the side of it. It didn’t feel moveable but now I think it is, as sometimes it’s more obvious than other times. It appears closer to the surface at times and other times it’s harder to find as it’s deeper a I don’t know if this is the position I was in when feeling. My breast is tender, and feels bruised/burning but I think that’s where I keep checked and prodding as it didn’t hurt before. Logically I know I need to stop feeling it (and stop reading about it) but it’s really hard as it’s constantly on my mind. I also know that the vast majority of lumps are harmless, but the reaction of the two doctors I’ve spoken to has increased my anxiety. I guess I’m just looking for reassurance that someone else had similar symptoms and it was nothing bad. 
I'm so sorry for the long post. You’re reading just part of my endless stream of thoughts, panic, and what ifs. My husband is being really supportive and is listening but I’m trying not to talk only about this - even though I’m only thinking about this. 
Thank you for reading/listening.
