It is important to get your feelings out. Write on PC, see a T, spend some time alone to work through things... Whatever works for you. But don't bottle things up.
I told a few friends - some have been really supportive, comfort and listen to me when that's what I need. Others didn't change their attitude, not even slightly.

Back at the place where I want my managers to know, but very scared of their reaction. I realise it makes sense to only disclose as a last resort at work
Your feelings are common. Vent as much as you need to. Work on educating yourself as much as possible too
