I am so incredibly moved by everyone's support and kind words. I read each of your replies several times and took the time to reflect over the weekend.
I feel like I don't deserve to talk about my struggles because I have so much to be grateful for...but I am slowly disappearing and I recognise my body is telling me that it has to stop because I am experiencing a host of negative physical and psychological symptoms/reactions that are really impacting my well-being.
I spoke to my gynaecologist last year, he says it's not too late to try for a child via IVF with my husband's frozen sperm. I asked him if he thought that my decision was selfish that I consciously choose to have a child knowing that he/she may not grow up with a father but he said he thinks it is not. However, he says I need to be mentally prepared that it will be an extremely challenging journey ahead with a high chance of failure, partly due to my age. I don't know if I am strong enough to do it (not my in current state of mind), also what if during my pregnancy or childbirth my husband has a recurrence? Am I capable of juggling between his medical care and taking care of a baby at the same time?
Saltygirl -- I am happy you're going to Mexico with your son!

Your status is similar to my husband's, are you on maintenance chemo? To answer your question, the reason I can't talk to my husband is because one of my worries is his death, how am I to talk about his passing when he's trying his best to be optimistic? Btw, I too have lived across 3 continent and managed to navigate through life in different languages... but I have no idea why I feel so weak and defeated now!!
Claudine -- I have been following you/husband's journey for quite some time. You've been truly remarkable and a great member of this forum. Thank you for that

Pantufla -- I read about your husband's situation. I know exactly how you feel! It's incredibly frustrating but I always tell myself that we can't control their lives. I told my husband that I am committed to provide him with the comfort and tools needed to stay healthy, but if he decides not to adopt it, there's absolutely nothing more I can do!
