Dear God don't do this.
Many parents raise children and work full time. If I had "full time mummy" and then a list of all the things mummy does, you would be filtered out by one of my staff and I'd never even see your CV. Although they did present me one once where there were genuinely emojis, but at least that applicant was a teenager, so marginally more excusable.
Being very real with you, because I don't think sugarcoating benefits anyone here, you need to up your game if you seriously want a job. If the only thing you've got experience of is being a dental nurse, then I'm going to assume you don't have any qualifications otherwise. So, your CV lands on my desk, and honestly, this is the review:
Qualifications, none: Ok, if I'm offering a menial/minimum wage position this isn't too much of an issue, let see how reliable you look.
Two kids: Well that's put you lower down the list than anyone with no kids or one kid. Because that's three people who could get ill that result in you not turning up. With no kids, I only have to worry about you being sick. Which leads me on to...
MH breakdown: If this is something you're disclosing, then I wouldn't hire you on that basis, not that my firm would ever admit it, but realistically that's a no thank you from 99% of firms. What with sick pay and rights from day one of employment now, and you've got history of long term sick? As an employer I see a liability waiting to happen. If I found out during your probation I'd find a reason not to continue your employment.
All three of those combined? Sorry but the likelihood of you being the preferred candidate above the multitude of applicants I'll have? Not good. I've hired 3 people at my business in the last 5 months. For those 3 roles, 2 of which are min wage, we had just over 600 applicants. One of our min wage hires holds a degree.
So, what can you do? Train yourself. In something useful. Can you do an evening course in Xero or QuickBooks, that would make you appealing for office work? The other thing is to put yourself on agency books and take what's put your way but it's likely to be production line. If you live near a Center Parcs, they are always hiring for housekeeping staff.
