IS THIS NORMAL OR AN ADDICTION?

lately I've been on the computer way to munch and i don't know what to do .I've been losing sleep so i'm very tired most of the time at work, i seem to be avoiding everyone even my own boyfriend.i make up excuses to not go out with people and it's not like i'm doing anything important on it.I get very emotional over the smallest things.and even my mom is getting fed up with me on it all the time.i don't know if anyone knows how to stop this?serious answer please
