OP, please don't ever say you 'feel like a single parent' to people you know who actually ARE single parents! As I imagine they would feel quite insulted!
You literally have no idea what a single parent has to deal with, and I hope for your sake you never have to find out.
A REAL single parent has this to deal with >>
Only one income coming into the household. No one to lean on for support. Having to do all household jobs, including gardening, decorating, fixing things, putting bins out, washing, ironing, cooking, shopping, as well as looking after Children at the same time, playing, helping with homework, sorting out arguments etc etc .
No freedom to just go out when you want to, having to plan literally everything. Being on your own with sick children, especially when you're unwell yourself is a nightmare. (And don't get me started on the stress you feel when you're having to sit with sick children in hospital A and E completely alone for instance in the middle of the night)
You have to work around school times, so often your work hours are limited, meaning less income to the ONE you have coming in.
You have to take time off work for appointments, or if your children are ill from School and you have no childcare. Shall I go on? Everything is totally relentless!
I have first hand experience as a GENUINE single parent, and even though I wouldn't change it for the World, as I've raised two amazing kids who I'm so proud of, it was very hard work.
Please don't play single parents down.
