I know this will probably sound incredibly stupid, but it is genuinely worrying me, and so I just have to ask. Anyway, I was kept up for most of last night by mosquitoes in my room (I somehow convinced myself they were carrying some nasty tropical disease, and spent a lot of the night trying to catch them all and take them outside, since I couldn't bear to actually kill them), and slept a total of somewhere between 4 and 5 hours. I feel exhausted now, but Mum says I still have to into work anyway. I'm worried that going in when I'm so tired might be bad for me, though (my legs feel really weak, and I'm worried that I might fall over or something like that). Is it safe to go in when I'm feeling like this?
