I feel sick

I'm thinking about the presentation tomorrow.
I've already come up with my speech and all.
Part of me wants to go and the other part couldn't leave the house at all.
Lately, I get hungry easily and yet taste nothing when I eat.
I wanna watch TV & play all day but I'll get tired and all sleepy.
I want to laugh and be happy and yet I'll get all sensitive and grumpy.
I thought I'm feeling all better but then all the throat & snot problem comes back on again.
Sigh.
And I feel so apologetic to my friends :(
for being emotionally unstable.
Sigh, I don't know why either. I guess things just happens unknowingly.
Now I just hope by getting back in health, everything will be right where it belongs.
& for this, I pray, hard.
