A death of a friend while pregnant

So today a very close friend of mine had committed suicide by walking out I front of a train, he was such a happy go lucky boy and the most genuine person ever! But last night he had one too many and everything got blown out of proportion apparently (I wasn't there as I cannot drink being halfway through pregnancy) so this afternoon he went missing without a phone call, any texts nothing and he committed suicide, there are so many questions but my main concern is this stress being put on my unborn child I don't want my baby stressed at all so I have had a good cry and tried to help myself feel better by a comedy etc. but it'll take my mind away for the time being and it's back and I can't stop crying? Has anyone dealt with grieving while pregnant I really do not handle situations like this very well nor lightly😓
