• Promote your own physical and emotional health by eating healthy, exercising, and getting plenty of rest.  Try relaxation and meditation.  Keep up with your own checkups and medical needs.
• Make a list of good things you can do for yourself and include one thing each day.  It might be things such as: seeing a movie, listening to music, taking a nap, journaling, going shopping, puttering in the yard, catching up on phone calls or e-mails, or taking a drive.  Remember that you will be better able to care for your loved one if you are taking care of yourself.
• Talk.  It's important to be able to talk about what you are going through also in caring for your loved one and dealing with the illness.  This may include talking to your loved one, family, or others who are a part of your support system. 
• Make a list of things that need to be done as well as people who might be able to help.  Know your limits and be prepared to ask for help from others when you need help or when others ask, "What can I do?"
• Educate yourself about their cancer, treatment and side effects.  Understand when it is important to contact the doctor and the best way to do so.  With your loved one's permission, be an active participant with their health care team.
• Know your legal rights.  Many employers are required to provide unpaid leave for family members who may need to take time off to care for a loved one.  This is provided under the Family Medical Leave Act.
• Find support.  If not through your family and friends, then join a support group in your community or on-line.  Other options might include talking with a mental health professional.
