Terrified nipple changes mean I have cancer - please help

Hello 

So two months ago I noticed one ignore my nipples was flat, with a split in it and some crusting. After a month I saw the GP and got an urgent referral.

 

The specialist at the hospital didn't seem worried and didn't do any tests. Just said use moisturiser. A month on I have used moisturiser, eczema cream and fucibet.

 

The nipple still looks pulled in and cracked and the surface is now uneven and sore looking. Doesn't hurt but itches a bit now and then. I'm terrified I have Paget's disease. I got so panicked I spoke to a dr online today an so she said from the picture it doesn't look too worrying but I don't know if they can really tell from a pic. 

Does anyone know if this sounds like cancer? Also can anxiety and depression cause cancer?
