I had a stretch of 3-4 good nights right before my last period, when I slept 10 pm to about 4 am straight and then fell back asleep for a while too, and I felt SO rested and had much more energy. Was less anxious and worried a whole lot less too. I really don't require so many hours of sleep, but they need to be quality hours. The ironic thing is that the days leading up to my period used to be the nights when I did NOT sleep well before. Everything is turned upside down with this hormonal garbage, I guess...
There's a lot of research about the importance of sleep to us - something that we neglect in this generation. The 8-10 hours of previous generations has been gradually cut to around 6 and it just doesn't give our bodies time to recover properly.

If the medics suspect there's something sinister, they tend to really rush it along - it's highly likely they're predicting some kind of IBS. colonitis or colon ulcers. Eating lots of fibre will help as it means everything is cleared out very regularly and not sticking around exacerbating the situation. Do keep pushing for treatment though, it's sad that you're suffering when there could be an easy remedy waiting for you after diagnosis.
I suffered debilitating insomnia last year and you really can't function properly. I've recently started taking Utrogestan and Oestrogel and my sleep patterns are returning to normal. The odd waking in the night if I'm stressed about work, but at least I can get back to sleep now rather than tossing and turning for hours. The oestrogen also will help the anxiety you're feeling.
Did your doc just give you a prescription for oestrogen, or progesterone too? It does need to be balanced by the latter if you have a womb.
I hope you manage to have a nap sometime during the day, you really will make yourself ill if you try and continue on with so little sleep.
