Sometimes I feel the same way. Sometimes I feel.... Like, well maybe you can guess..
But I always think about how sad my friends and family would be if I did it. Maybe think about how amazing you are, and how much everybody would miss you. And, please, please, please, don't give in to the impulsive/intrusive thoughts. If you did.. You'd regret it later, I'm positive.
