Over night :/

I slept for a long time last night. I think I went to bed at 8pm and got up at a little before 6am! I really hate the sense of sadness I feel. Like Ive lost my best friend or something! lol But I feel so sleepy...no energy at all. Is that apart of the quitting...the withdraws?? I hope it passes soon!
