Hi Leila. Welcome, but sorry you had to join us here. It's a scary time when you are first diagnosed. I remember having a lot of questions and being anxious. But 'surreal' sums up what I was feeling. I was in the private system and had a 4 week wait for surgery because the surgeon I choose was in high demand.
Like Kath said, you can use same toilet with chemo just flush twice with the lid down. It can be hard to be around sick kids during chemo you may want to wear a mask if they have a sore throat or cold and you will have to wash your hands a lot. You can't make others sick.
Since you have bad veins you may want to ask your doctor about having a portacath inserted. Chemo really damages your veins which can be a problem for some. A portacath goes under your skin in your chest and is used to deliver your chemo via IV. It means you can avoid using the veins in your arms for bloods and chemo. Another option is a PICC line in your arm. You get a lot of needles during chemo (some for blood, some for chemo, some for other drugs if you get sick) so it may be worth it. Other people get through fine without a port of a picc line.
Like Kath I couldn't work through chemo but I did work through radiation. Everyone is different.
Best of luck. Come on here and ask anything, any time.
Take care
Nadine
