I'm 15 turning 16 in September I keep really worrying about my breasts to the point I'm not eating much at all. 

I've noticed only one of my nipples are inverted or at least have a noticeable slit in it that I hate. It does come out upon stimulation but it does not look the same as my other nipple which really bothers me.

Also both of my breasts have bright blue veins, though I am incredibly pale but im not sure if this is normal.

I feel my breasts and look at them several times a day its like a fear thing whenever I see myself in a mirror alone I get the urge to check and look and so I do, and of course I see everything I mentioned and get worried but I havent found a lump that isn't exactly the same on both breasts, probably normal lumps, as of yet

I'm wondering if this is normal or worth speaking to somebody about. I wanted to tell a teacher about it today but I was too scared and shy and left in tears for the whole day, my fear is getting out of hand and I'm sick of it I recovered from anorexia slightly now im eating way too little calories because im scared that I'll make the cancer grow if I even have it. I'm just so tired of everything.
