Hi, wow you have a lot going on, and it will never ever be a good time to find out about medical challenges.
Feel free to read though my last 12 months journey blog (time to process)...I was diagnosed just before christmas 2023 and have spent 2024 going through treatments (er pr +, her -, lumpectomy, with advanced regional stage 3 due to lymph node involvement, so chemo, radiotherapy and now hormone blockers). There is no getting around it is tough to process!.
I had a few people I knew that been through their b.c. journeys, and was able to message them, that helped me when I was particularly feeling low... so finding some help, whoever and where ever it may be, to support you is so important. Sounds like you have massive life changes ahead, so take any positives you can, and try to find some mental head space for yourself. And reach out to anyone you feel comfortable to trust. One day at a time!
