I am so sorry you are having to go through this - big cyber hug.
I am also TNBC, and would like to send you a link to an international website, to the long term survivors page. Here are women - some with secondaries - who are 11 years out and still going strong. It is encouraging to read their comments and I think we need all the positive information we can get.
The link is https://community.breastcancer.org/forum/72/topic/815872.
Stay in touch and let us know your program. There is so much research going into TNBC now. It gets better every year. Just take one day at a time, Jenny. We are all here for you. xxx Michelle
