People deal with serious problems in different ways. It's hard to predict how living with cancer will affect you.
Having cancer can lead to a range of emotions. These may include shock, anxiety, relief, sadness and depression.
Being open and honest about how you feel and what your family and friends can do to help you may put others at ease. Don't feel shy about telling people that you need some time to yourself, if that's what you need.
Your doctor or specialist may be able to reassure you if you have questions, or you may find it helpful to talk to a trained counsellor, psychologist or call specialist helplines.
Patient organisations have local groups where you can meet other people who have been diagnosed with cancer and have had treatment.
If you have feelings of depression, talk to your doctor who will be able to provide advice and support.
