Grieving while pregnant - Advice?

Samantha

Last night, my 14-year-old nephew died suddenly while playing basketball. We were told cardiomyopathy- His heart just stopped.... He was an amazing and healthy young man.

None of this feels real...

But, how on earth do I handle this while 32 weeks pregnant? I don't want to stress and have it effect my baby. But, I need to grieve my nephew... Every time I start to break down, I have to force myself to stop and relax... What do I do? Has anyone else dealt with loss while pregnant?
