I dont feel well

I got sent home from work 2day, i didnt feel very well. I could have stayed i think but they told me not too & they said not to go in tomorrow. Trouble is i needed 2 pull a sicky on thursday as i have my theory exam. Oooh noooo. now im stuffed. I feel really shitty (excuse the french). I feel really exhausted. its not like i do much to get exhausted. My mum reckons its stress & the routine that i am in (i stay at my bfriends everynight & he drops me home at 6.30 in the morning on his way to work, then i have to get ready & go out the door for work). Every half hour i feel my eyes welling up with tears...oh god what have i turned into. This makes me feel guilty cos i have absolutely nothing to be stressed about apart from my work & money situation. Maybe a trip to the docs is in order. aaarrrgggghhh i dont know. My belly hurts! x x x
