Aaaand I'm ill again

I have a cold again. I felt fine yesterday morning, but then as the day went on I started feeling more and more blocked up and got a scratchy throat. Then this morning I woke up and could barely breathe. This is so irritating. I obviously caught if from my mum as she was ill last week, but at the time I thought I'd be fine so didn't make any attempt to stay away from her. I really hope I'm okay for the vegan festival on Sunday, I'll be so annoyed if I'm too ill to go. Fingers crossed :s
