what is wrong with me?

i dun know what is happening to me...i have been feeling so tired even since taking the june holiday programmes...every night when i plopped into bed, i just fall into deep sleep immediately but when i am up, i feel tired again...it is as though i did not rest enough..even during the weekends and i get up later, i still feel tired within 2 hours...i really dun know what is wrong with me..too exhausted that my body is breaking down?...i dun know...i really hope that there is nothing wrong with me..daddy claims that i am just being lazy..i dun think so..i just feel so sluggish..not eating too well too...is it stress?well i dun think it is that stressful now...i mean i have been through worse periods in my life...just cannot put a finger to what is wrong...next week, work will ease slightly with the help of another teacher...not that much but better than nothing...hope that i am really not sick..and nope ppl, i am not pregnant..my period just ended..so dun jump to that conclusion ok?
