overwhelmed!!

Hi,   I got diagnosed with Secondary breast cancer in my lungs 6 weeks ago (20 April )  After going through breast cancer in 2014 which resulted in a mastectomy and 12 months of chemo....then got hit with the news that it has spread to my lungs.... since then I have had my port put back in and two chemo sessions. I am feeling lost and overwhelmed of what I should be doing. I have had to stop work  which has put a stain on my family  and im not sure where to turn or what to do.....   Any help/advice would be great....Thanks
