Sketchy mole,potentially bad news?

I have had this mole on my back for about 1-1.5 years now, stupid of me but I never realy pay attention to it , my roommate noticed it today and told me I should go to a dermatologist , should I be worried? I will try to go on Monday.

Yes , go quickly to a dermatologist , don’t wait , even if it turns out benign.
