Ww2 breast clinic worries

Hi, l visited my GP Monday after discovering a small pea sized lump in my right breast, an emergency referral was made straight away. The rational part of my brain says all will be well .. probably just a cyst, the irrational part is freaking out. It looks like I'm going to have to wait longer than 2 weeks due to a backlog at the clinic which is totally understandable but means even longer to worry !!
