Should I go to sleep its 2:57 in the morning n im really tired but dont wanna sleep but im tired

Yes, i do think you should go to sleep.

You're body is trying to tell you to rest by making you feel tired. Sleep is a way for the body to reset itself and prepare for the next day. If you don't want to sleep, try listening to relaxing noises, like asmr or nature sounds. You could also try; with parent permission; taking sleep medication. Another way is to turn your electronics off and laying in your bed for a while.
