Stage 4 cancer, making memories family security

Hi there I'm Lucy Canavan 36 years old from Stockport, Greater Manchester.

Earlier this year after finding 3 lumps, 2 in breast 1 in armpit I went immediately to my GP. They prescribed me antibiotics telling me it was more than likely an infection, nothing to worry about and cos of my age nothing serious. Fast forward to June 22nd 2021 and I'm diagnosed with breast cancer. Fast forward a few more week after many appointments, biopsies & scans I'm diagnosed with Stage 4 breast cancer with spread in lymphnodes, armpit/neck and spread to liver.

August this year I married my partner of 19 years, should have happened last year but was rescheduled a few times, thanks covid, and because of diagnosis and docs telling me I'd already be in treatment cancelled the wedding reception we had planned, which wasn't the case and most definitely could of had the big bash we had planned before treatment started. (Thanks doctors)

My husband (still so odd to say that) has also been off work the past 3 month due to complications caused from when we had covid back in Feb. He developed a blood clot on lung (pulmonary embolism) and pneumonia. So to say this year hasn't been kind to us is abit of understatement, and since he's been off work money is incredibly tight. I'm currently still working when and where I can if the side affects of my chemotherapy let me, working for NHS 119 Covid 19 testing booking service but is becoming more difficult not only physically but from a mental stand point too. 

We have 3 young children twin boys Dexter & Rory age 7 and Luna age 5. The prognosis with stage 4 breast cancer is 2/3 years, I'm hopeful this won't be the case but I'm wanting to create as many memories as possible for my young family, leave them with a bit of security when I'm gone, not the mess of sorting my funeral and also if possible any money to go towards treatments if possible/needed.

Any help no matter how big or small is very much appreciated! Thank you so, so much
