Oh yes...I am the same way. Oh god...every time I hear "Every Rose Has Its Thorn" or "Lips of An Angel" I want to curl up into a little ball and become dust and just blow away in the wind. They remind me of someone I have not been able to get over for four years now...and they still love me too. But hes 4 years older than me, and I'm still 17 so, its been killing me. And these things make me go back in time in my head...its so hard...but it happens all of the time. It is actually the very core of my depression and the severity of it.
