I am very, very sorry for your loss. I don't have direct experience with losing a child. I only know what I learned from my aunt - who is more like a sister - after she lost her almost 2 year old very suddenly.
She grieved her way. She got help from a psychiatrist who prescribed something mild to help her with her depression and forced herself to do some of the things that she enjoyed before losing her son. Having to watch out for her 7 year old son also helped her.
My other aunt lost her son a week before he turned 30 years old after fighting colon cancer for 6 years. This was a very different experience and she is grieving in a very different way.
From their experiences, I know that the first year or so of grieving is the most difficult and then slowly things get better.
The one thing both my aunts have in common is that they both rely heavily on their friends and family. Also, they have never avoided speaking of their sons and have asked of friends and family to not feel like they are walking on eggshells around them. The result is that when I see them, if I remember something about my cousins, we share the memory and it's part of the conversation.
I don't know the circumstances of your son's passing. I hope these stories help you and know that this is a huge pain that takes time to transform into less painful memories. It is not a pain that heals and goes away. It just slowly becomes something that is easier to bear. Let yourself feel the pain whenever you need to, don't just hold it in or try to set it aside.
I come from a big family and went through about 5 years when I lost someone close each year.
Have courage. Take care of yourself. Find someone to talk to.
