everyday i would wake up and say "its a new day"  i would always wait for that "new day" to come, but ever since 3 weeks ago every day feels the same. I do not know if i am happy, but i am not depressed. I honestly do not know what is wrong with me! felling this way all the time sucks! I just want things to go back to the way they were. Back to the times when i was happy. Back to the times when there was not a care in the world
