Welcom to the group Tanya and sorry for the reason for joining.
It is all a bit overwhelming and kind of full of confusion and uncertainty when you are diagnosed and before the active treatment starts.
Everyone is different and even on the same Chemo regime we all react a little bit differently and our bodies react differently. Some can work and others cannot and you probably will not know how your body will react until Chemo starts. It is good to plan for not being able to work just in case and also to talk to the employer about some flexible working arrangements like working from home if that is an option at all as there may be days when your body simply will not allow you to leave the home.
Also if you have any type of income insurance worth checking with them if and how your policy may kick in if unable to work plus most superannuation plans have an inbuilt feature where you get income protection where cancer treatment qualifies you for a benefit of up to 75% of your salary after 3 months.
Kids are resiliant so may be worthwhile preparing them slowly (especially if you will be on a regime that involves heairloss). A friend had 3 little ones of similar ages to yourself when she was first diagnosed and they did explain to the kids that mum had to take medicine that would make her hair fall off well in advance. She also got a rather short boyish cut 1 week before her 1st Chemo and she made it a family affair where kids helped choose the cut from the hair magazine and accompanied her to the hairdresser (she had always had long hair prior to that so kids had never seen her with short hair).
She also took them shopping for caps and headwear where they helped pick the appropriate headwear. Funny how quickly kids adjust to the new look plus being involved made them not as worried. And then 1 week after 1st Chemo she went for a crew cut again with the kids and 2 weeks later as hair started to shed she had it shaved completely. She made every trip a family affair and also because it was a slow staged approach kids did not get shocked as each new cut was not hugely different from the one before.
Not sure if something like what she did would help you if your treatment is going to imvolve hairloss.
In any way do take it easy for now. There is a lot to digest and it takes time to get past the diagnosis and the idea of the treatments to come. I remmeber when I was diagnosed back end of February and trying to prepare so my life would not change much only to be knocked flat on my backside time and time again as I was denying what was going on and thinking I could control the course of what would come.
I guess we have to plan for the worst; hope for the best and not forget we are human afterall and what is happening to us is way way way out of the ordinary and since there is so much in here that is out of our control; emotions and behaviours (not to mention body responses to various treatments) we never thought would happen to us can and they will happen.
Whatever does come remember everyone here has been through it or is going through it and we do get it. If you have to be strong for others this is one safe place where we get it and there is no judgement as we really do get it - so be it information you need, a chat, a whinge, good old sooking or an outright meltdown we will get it and will be here for you.
Wishing you all the best and a lot of strength in comming days.
Hugs
