Two week pathway?

Hello I am waiting for an appointment for a breast lump but been told by someone that after the two weeks they are now not getting seen till end of December. I am going out of my mind and today have been Googling and convinced myself I have secondary cancer too. I haven't even had a diagnosis yet ‍♀️ It doesn't help that the lump is so large I can't even wear a bra comfortably so I'm reminded of it all the time! I would really appreciate advise from anyone thanks in advance.
