"Coping Strategies
Join a support group and you can share your story in a non-judgmental environment. You will likely make contact with other suicide survivors and they will understand exactly what you're going through.
The raw emotions you will feel after a suicide can overwhelm you physically and mentally. If these feelings continue unresolved for a long time you'll end up harming yourself, so it's important to find some professional therapy. You must talk about what you're feeling.
Don't let anybody rush you through the grieving process. Take as much time as you need. Ask for an extended leave of absence from work if you feel it's necessary.
Take care of yourself, and get plenty of rest.
Get your anger out! You may not want to admit it, but it's there and it must be recognized. Scream, shout, cry or pound your fists against a pillow. Any of these will be helpful as long as your emotions do not stay locked up.
Things You Shouldn't Do
Never place the blame on yourself or on the deceased. It's nobody's fault.
Avoid prescription medications and alcohol to cope with grief. They will only serve to lift your mood artificially and will not treat the real cause, which is the loss itself.
Do not let anyone else tell you how to feel, or to convince you that it's time to snap out of it and move on with your life. Remarks of this nature are presumptuous and inappropriate.
