Hello... I hope you are coping with your new circumstances and healing well from your TURBT. You did not indicate whether you have other family who can help, or any other type of support network of trusted friends or neighbors.
If you do, please let them know what is happening. Many will want to help you on days you may need to rest. If you have those people in your life, perhaps you could begin to let them know and help with some of your routine things so they will know what to do when you need some assistance. It might also help your little ones get used to another person being around to help mom sometimes.
My heart goes out to you because I know you feel trapped in a situation that you don't have time to deal with, but you have to for all of you. BCG has proven to be very successful for many people and I hope the same for you. Please come back to the forum whenever you need to talk. We will try to answer your questions, or just listen to your worries. We're pretty good at that.
Take care... Catherine
