When I was on zopiclone I was still able to wake up to see to my son :) if anything I was more alert especially when I heard the tiniest noise, I think it just helps you drift off and feel a little more rested. Definitely agree not to take them in the day though!
Give rescue remedy a try! I've used a few of their products, maybe give the chewing gum a try, I used to take them before a driving lesson an really calmed my nerves
I also used to use the rescue remedy night version in the little bottle, a couple of drops on your tongue or in a glass of water before bed and I'd ( still do) whack on a podcast for relaxation.
Search on the iTunes store or Android store for " Joseph Clough" the guy is a godsend with so many free podcasts you can listen to or download, has a selection of hypnosis tracks or just general tracks about how to manage anxiety, moods etc. He was brilliant and I found I was so calm I'd drift off before it even got into the session
I suffer anxiety and also have suffered insomnia for years an I know what it's like when you're running on empty. My son is teething and waking up at 5/5.30am atm and it's killing me through my lack of sleep so I do understand on that front
You can also download quite a good selection of apps to help such as CBT and other apps :)
Take a look and give a couple a try.
Don't be scared to take your sleeping, I was so frightened at first when I was prescribed them but the next morning my mum even turned round and said how refreshed and glowing I was looking, and that was just one night managing to get a good sleep
I think the children are best where they are for the minute, but I'd urge you to use this time to focus on your health and hopefully the dust will settle and you'll feel more in control of your emotions
I hope atleast one little bit of what I've written helps in some way
