Here we go again - lump and nipple change

So one year ago I found my first lump. Hardly slept for the 2 weeks it took for the appointment with a consultant who was vile. Positive was that I was given all clear and dismissed - literally. So tomorrow I have another appointment. First lump still there buy now have second lump/ridge in other breast and nipple has changed shape ( not inverted but different shape sometimes). Have been pretty relaxed about appointment as last time I worried so much but needless to say I’m now in a panic. Sure it will all be fine but mind full of all the what ifs.
