Sleepless with a heavy heart

I was jolted from my sleep at 1am with a very loud and racing heartbeat. The rate was so rapid that i was afraid it'll pop out of my chest. Tried going back to sleep but decided to get up instead. Went and did some ironing at the stuffy guestroom to avoid the blardy mosquitoes. Finished around 3am and havent been able to sleep a wink till now. The room is already starting to brighten up with the sunrays streaming in. Both kids slept soundly through the night. I'm waiting for hubby's return so that we can have a heart to heart talk. Just pray the kids will allow us to do just that by sleeping early tonight.
