No you shouldn't. Don't ever think that, I may not fully understand your emotions and what your feeling, but I have felt bad in the past. I have thought of "What would happen if I were to die right now? Would anyone care?" I didn't think anyone did, everyone kept bullying me at school, my sister was always rude to me and verbally abused me while my parents were out. Just think, "What do I love to do?" and "If I were to die, I wouldn't be able to do so many things I love." My escape was drawing, you should try and come up with something that helps you express yourself, whether it be drawing, writing, comedy, YouTube videos or even animations. It helps a lot.
By the way, this is coming from a thirteen year old, you shouldn't take what I say too seriously. Just so you know.
