i am Sick again

just came back from tiring hongkong trip.
nose phlegm got blood.
face too dry
headache and body aching..
its coldddd
yet i have to sit in such a heavy place.
its so torturing...
god please....
why am i getting sick always.. have i neglected my health recently?.. well, i guess i cant remember when was the last time i exercise..
i hate falling sick.. its so lonely.. cause you feel helpless but you cant request for more.. cause its useless and you wont get it when you request for more care...
i just dont like it.. being so weak without someone here for me.. its so lonely..
sigh.. what have i done.. why is it has to be me?
