Welcome @JoeyLiz. Although we don't choose to be here, it's a great place to share the journey.
I'm 29, married with no kids, and just finished 5 months of chemo AC, Paclitaxol and started Herceptin. My surgery for a double mastectomy, node clearance RH side and sentinel node LH side is booked for 16th Nov, 4 days after my 30th birthday. I have BC in both breasts and it had spread to the right lymph nodes.
I think you've got to do whatever it takes for you to get through this. I was told similar that I was handling things well. I just didn't know what the alternative would be. I couldn't change anything. I still had to do it all whether I liked it or not, so I just got on with it. I allowed myself to just feel whatever I was feeling and then get on with it. It's not always easy but fighting how you feel is too hard during this process anyway. I also allowed myself some seriously morbid jokes with my husband just to get it out. But for me, I use humour to diffuse serious situations so I don't go insane.
You've got this. Cheers, Jen.
