Welcome to the forum. I’m 17 months post diagnosis and I’m Er+ HER2+ bi lateral invasive cancer, two primary one in each boob, grade 1 and a grade 2. So I can understand how you feel.
As already mentioned the chemo starters group are a fantastic support. There is also a thread for HER2 buddies that is very popular. I’ve only just finished my year of Herceptin and it’s a great support network.
