feed a what starve a what?

i've been a little ill this week. every morning i have dragged myself out of bed but crawled back for another hour. luckily i am working lates this week so it doesn;t matter.
just wondering when you get a cold or flu you do something different?. i though i might be able to exercise it out lol or do you chill for the week and eat less?
i was so miserable yesterday at work with no food that i went to the chinese and had curry rice and chips in a tray and man that cheered me right up but today feeling a little better im like what?!!!! dumba** im getting so close overall with my goals but i have been over and around 12st 3 for weeks now. i really thought after getting into the exercise thing last week that things would change but feeling ill is kiling me. i did five minutes on the bike this morning before feeling so tired i nearly passed out. (drama queen i know).
what do you do when you are ill.
plus its gone form like 17-18 degress C 54F i suppose to in the 80's in like a week so its so hot every where my head feels like it might explode (yes i did say i was a drama queen).
sorta male venting going on here lol.
also one more thing. could this be my body saying welcome to the world of exercise lol i erally haven;t done anything till now.
im going to go hide round the back of the office now and do star jumps till the calorie counter stop saying minus figures lol
