Is something actually wrong with me, or am I just your typical screwed up teenager?

a ton of your bullet points apply to me too... but u seam to think about them more. No worries i dont think that your crazy like the suicide thing... the fact that its suicide might be a little weird but everyone thinks about dieing in some crazy way and how their friends and family would act. as far as the romantic thing... it kinda depends on how old you are... you might just grow out of it or you might always just be a little nervous about it.
