I'm sorry to read about your Mum's diagnosis. As well as the support you recieve here if you need to talk things through do give the BCC helpline a call on 0808 800 6000. Here you can share your feelings and concerns with someone who will offer you emotional support as well as practical information. The lines are open Monday to Friday 9 to 5pm and Saturday 10 to 2pm.
Best wishes Sam, BCC Facilitator
