Hi I'm a 20 year old who recently developed HA and I found a new mole on my back a couple months ago around July I never remembered having a mole on my back at all so I'm guessing it's new and It been causing me nothing but trouble I'm obsessed with it I look at it a bunch of times whenever in the bathroom or pass a mirror I look at it I've a derm look at but she only looked at it for like 2-3 seconds and said looked fine but we'll keep an eye on it from what I can tell it's not that big smaller than pencil eraser maybe as big as mechanical pencil tip so I'll say .7mm maybe a little bigger idk as far as i can tell all one color and maybe symmetrical hard to tell by myself but my HA convinced me it's melanoma and I can't stop thinking it is and I keep having panic attacks worrying.
