Fatigue, fatigue, fatigue

Daughter does not have school on Friday's so I have her all day. I was fine until I left the house. Then I started to get extremely tired & out of it. Just wanted to get home but had to keep shopping. Took one Ativan in Hobby store. Takes about 15-20 min to kick in. Went home took a 3 hr nap. Fell better but I want coffee or something to fill the emptiness that is always present. I bought too many things I did not need today and used my business cc so my husband would not find out. I just don't want him to think I am manic.
