Work was very supportive of me during that time, excluding my direct supervisor, who nearly ended up being fired over it. I had support from friends that helped as well.
But it being a suicide added so much more taboo to it. His birth giving parent (is a trans man) was raised very religious and had a hard time telling people it was a suicide, so I kept it quiet. Eventually they announced the suicide and me being able to talk about it in that sense really helped me a lot.
Please find someone with whom you can talk.
