There are many things you can do to help yourself cope during this time. Ask for help and support from family, friends or a support group, and try to express whatever you are feeling, be it anger, guilt or sadness.
Accept that some things like death are beyond your control. Avoid making major decisions - your judgement may be off kilter and changes could increase your stress levels. Give yourself the time and space to grieve. By doing so, you will be able to mourn properly and avoid problems in the future.
Remember to keep in touch with your doctor. If you are having sleeping problems, your doctor may prescribe sleeping tablets or may refer you to a counsellor if you feel the need for more help to cope with a loss.
