Abnormal wrinkle on lip-giving me intense stress!!

I'm not worried about it all that much. I got it checked out when I went to get tested for stds the doc said it was nothing but a wrinkle and for me to calm down. You have no idea how stressed I was about it! When she would check my blood pressure she was ready to send me to emergency. I'm much calmer now that she told me it's not a std.

She said to give it time to see if it goes away and to calm down. It's been almost two weeks since I first saw this thing on my lip. There's not pain, no color, nothing! You see it sometimes and most of the times you can see it. There's no bumps or anything it looks like a raised wrinkle on my lip.And when you touch it you feel nothing it just smoothes out. It's more noticeable when I bend my lip and such like how a wrinkle would react and it's not noticable when my lips are totally relaxed but that's only sometimes. And it's only ONE wrinkle. It hasn't gotten better but it hasn't gotten worse either; it's just hanging out on my lip. And it's causing me major stress because I think when people kinda notice it they they I have something! The doc says I'm find and I can kiss and such but I dunno.I told her should I go to a dermotoligist or any other docs and she said to not waste my money and they would laugh at how much i'm fussing.

I looked all over the internet and there is NOTHING that is similar to what I have going on.... is it lip cancer? I don't smoke or anything like that. Or is it stressed related. Like how when you get a twitch in your eye or a stress vein in my lip? because before I noticed it i have been stressed about what's going on in my house to the point where I would shake or nearly faint. help. help.
