From another mother that lost her only daughter.... YOU have to find a reason to want to live again, to be there for the family members you are still blessed to have - they NEED you!
One way I found to get past the guilt and hurdle of not having my precious little girl around any more was to write her a letter, telling her how much we missed her - loved her - and how sorry I was for the things we would never do together.... then I took the letter to the grave site and dug a hole by her foot stone and buried it - away from seeing eyes.... this letter of deep emotions and pain was to be just between Her, God and Myself.
AND - of course time does help and heals all wounds.... it personally took 4 years for my family: my husband, our two sons and myself to learn to live again.... to have happiness without her in our lives.
