26 and freaking.

Hey ladies. About three years ago I found a lump in my right breast. Had an ultrasound and it came back as a fibroademona and no one was concerned. I’ve had it scanned yearly since and just last week got the okay to move to two yearly + scans. 
A few days ago I was in the bathroom and when drying my hair I noticed an indent in my other (right) breast but didn’t think much of it as I was wearing a pretty awful bra that day. Last night I was doing my monthly breast check and when I lift my arms above my head the indent is still there. It’s about 1.5cm above and slightly anterior to my nipple and only visible with arms up. I am freaking out. I have very severe anxiety and my meds aren’t even touching the edges with it today. I did the worst thing known to man and googled and while there are lots of varied lump stories (mine included) the ones starting with “I found an indent” seem to all end with C.
