Coping with looking and feeling different
Outward changes, such as skin problems or losing your hair, can make you feel self-conscious. Even changes that aren't as visible, such as feeling tired or a hidden scar, can make you feel differently about yourself. It may help to remember that most teens feel self-conscious at times and that's normal. These tips may help you cope with looking and feeling different:
- Give yourself time to get used to your new appearance and adjust to your body.
- Remember that many body changes, such as hair loss or weight gain, are only temporary. Some permanent changes, such as scars, will become less noticeable over time.
- Talk with other teens with cancer about how they cope with their body changes.
- Be prepared for questions and comments about your appearance. Decide how much you want to tell people and think about how you'll answer questions. If you prefer not to talk about it, just tell your friends that it's private.
- Remember that while your body may look and feel different, you're still the same person on the inside. The qualities that make you unique and special aren't changed by cancer.
- If you're feeling overwhelmed by the changes in your body, ask your doctor for a referral to a counselor or a social worker. Learn more about finding help and support .
