I felt really tired this morning. I didn't want to get up and go to work. I just wanted to lay in bed with my boyfriend all day. I went to bed at 10 last night a lot earlier than usual me and him and his friends usually stay up till 1 or midnight but I just felt so tired. Its only 5:30 and in tired right now. I'm not pregnant or in my period and I'm not sick. What's wrong with me ? Is it normal to feel so tired ?
