How do I move past the grief of a family suicide?

You don't really move past it. You go through a process, which might require help and isn't always linear, in which you come to terms with it as best you can and prevent from having any furthur impact on it beyond what is unavoidable. This will never change the fact of the person being dead or the fact that the suicide was a wrongful act.

If I were you, I would not do it alone. Get some professional assistance.

Good luck and take care!

You should seek the medical advice of a mental professional. Therapists, psychiatrist, etc.

One day at a time. Understand that the family member was sick and for whatever reason could not ask for help. It is sad, but you did not cause them to commit suicide. So do not blame yourself. Remember the family member in better times. Those memories will be with you forever!

Boy this is a tough one. I have been through it myself. Time first off will help a bit... Mine was 26 years ago and there are still moments when I cry. But I have come to understand (in my case) that mental illness is out of my control. There was nothing I could have done to prevent this person from having committed suicide. Some people have sunk so low into depression that they are just determined to end it all inspite of help. You can't blame yourself for what happened but please know that time will help you to deal with it and put it in its place to where you won't feel the grief all the time

I don't think you ever really get over it. I don't have any family that has committed suicide, but one of my best-friends did, and I loved her very much.
On top of grieving for the love one that committed suicide, you're also angry and hurt, and always wondering if you could have done something. We are told the signs of a suicidal person, but sometimes, like in the case of my friend, there honestly aren't any signs. I remember sitting down with our other friends, as well as my friends family and trying to to figure out how we had missed her plan to kill herself, but I swear, there wasn't anything that we saw. She never said anything about being depressed, and up until the very day she died, she just seemed happy with life. A note that she left told us a different story. She said she felt like she was fighting daemons her head, and she just couldn't handle the depression and emptiness that she felt.
You need to talk to people that have been through what you're going through now. I'm sure you're feeling what most survivors of suicide are feeling. You wonder what you could have done to stop it. But it's not your fault.
There is a really good web-site you should visit. it's called Survivors of Suicide, and their web address is www.survivorsofsuicide.com
I wish you the best of luck. Give yourself time to grieve. You never totally get over it, but you learn how to live with and come to terms with it. Take care of yourself.

sorry but i don't know if you ever really do. and, of course everyone is different in their own griefing process.

myself, even though i've tried, and obviously failed suicide twice have lost a close aunt to suicide 11 years ago this past june 18th and there has not been a day past that i have not thought of her.

it is a really tough thing to go thru, i don't think for sure you ever get past it. and unfortunately i am still having suicidal thoughts to get thru myself.
