I am so so sorry to hear of the tragic loss of your son. I lost my son to stillbirth in May of last year. He was born sleeping at 34.5 weeks.
I am a member of Dailystrength.org. Dailystrength has support groups online for parents who have experienced a stillbirth. There are also groups that support women TTC after stillbirth, and beyond.
I cannot recommend this site enough. The women on there are extremely supportive, and there are many women who post pictures of their angels on there. Here is the link to the stillbirth support group: http://www.dailystrength.org/c/Stillbirth/support-group
I don't think I would have made it through the last eight months without all of the support I've received from the women on that site.
Please know that there was nothing you could have done to save your son, and none of what happened was your fault.
The pain of losing your child this way is agonizing. There are no real explanations or words that will give you comfort. Just know that there are other women out there who have experienced, and are experiencing the same thoughts and feelings as you. The pain and agony of losing your child to Stillbirth is so totally devastating. Only those who have experienced the same pain can truly understand what you're going through.
You are in my thoughts and prayers.
