Hello Mummy; welcome to the forum but desperately sorry with the hand that fate has dealt you.  This is the cruellest fate knowing that your husband and son will be left without you and your son will grow up without you being around.  Don't try to be strong all the time; you need to get your tears out and I hope if you do this you will feel better able to cope with your fate.  I expect you have been given information about creating memory boxes with photos, letters to be read etc.  I don't know how long ago you received the dreadful prognosis and hope that you are getting support from, say, MacMillan Cancer Support (Freefone 0808 808 0000).  I feel I am writing in a very clumsy manner because there is nothing I can really do to help you through this but I wanted you to know that we are here to listen (read really) to your fears and feelings at any time.  Sadly there will be others in your position who I hope will contact you.  Annie
