I was utterly overwhelmed working FT, with 2 primary aged DC with SN. (I burnt out. Twice).
I now work PT self employed but there are still many days when I struggle.
DC2 has weekly, bi-weekly, monthly, 6 monthly and annual medical appointments that I need to keep on top of.
DC1 has monthly, 6 weekly, 6 monthly and annual medical appointments.
DC1 is also currently being investigated for something which has required 3 Dr appointments, 1 scan and a blood test so far.
Both do 2 sessions of sport clubs a week plus occasional weekend competitions.
We have no family or friend support network (recently moved overseas).
DH does what he can but is a C suite executive so has MANY responsibilities through work. The plus side is that money is the one thing I don't have to worry about.
Last year my DS2 missed 50% of his school time: through school refusal, strikes, illness and teacher absence. Suffice to say, I struggled a LOT! (Especially with never knowing if school was going to call me to collect him).
There are so many variables. I would be a lot less overwhelmed and stressed if I had 2 generally healthy NT kids and I could safely work without worrying about being called to school. Or how I'm going to fit in all the appointments.
I was once talking to a colleague and saying how my stress levels rose every time my mobile rang at work. She was astonished because she just dropped her DD off at school and didn't think about her again until it was time to pick her up from ASC.
