I have stage 4 bone marrow cancer with about 8 weeks left

Hi my name is Laura im 53 years old and I have stage 4 bone marrow cancer acute myeloid . I have a 23 yr old son who I will be leaving behind , my mum also died off the same cancer in 1981 age 39 . I have blood transfusions every two weeks in Slough hospital, i would love to have a little holiday with my son so he can make his last memory with me by the sea . I would love to go to Portsmouth and have a little paddle and at a push maybe a little ice cream. But my dieing wish would be watching the sun set with my son by the sea and take lots off photos . And I want to book my funeral so it can be a time off joy not sadness. , I would be so grateful if you could help.
