I'm 37 weeks pregnant and for the the past 2 days I haven't slept a wink. It's been happening on and off for a few weeks but this past week I feel like I'm functioning on an hours sleep. I feel so upset, emotional and angry. I just want to be able to close my eyes and sleep but I can't switch off. Do you have any tips or remedies please? I work all day in a very active job but as soon as I'm home my body starts to ache and I become so irritable. Please help as I feel like I'm losing my mind and it's really affecting what has been an otherwise lovely pregnancy.
