Well you're pretty much the only one who knows what you can relate to, but from your profile's "About Me", I'd say: https://www.youtube.com/watch?v=NVVrT_wNw_Y
I personally relate to some rap songs like Brainless by Eminem, Recluse by Plan B, Am I A Psycho by Tech N9ne and some French-speaking rap you would probably not understand anyways, but you might not like rap, I don't know. Sum 41 has pretty good overall songs about peoples with "problems". I'm a huge fan of their music, so I can give you songs accordingly to what you want to relate to. Pretty neat song that everybody could relate to by them: https://www.youtube.com/watch?v=yl2hYHCzM8g
