nauseous

i hadn't eaten a real meal or barely anything in a few days. i wasn't feeling very active or hungry. today i actually got out of the house and in turn i ate a real meal. now i'm feeling so nauseous. all i want to do now is lay in bed and go to sleep, which really goes against my whole "productive" day of getting out of the house. i actually hate having a productive day because then the next day is always so horrible. i can only be productive for so long and then the desire is gone. i am not looking forward to tomorrow because i know it will be a day full of sleep and nothingness.
