Sorry for your loss
Hopefully you'll find it supportive being here, it's a lovely group
For work, as management are being rubbish are you close to any colleagues, who can help it feel more welcoming to come back? There is a chance they are meaning well but getting it wrong - my boss decided to stop my team doing a card or flowers as he thought I wouldnt like it, so i didnt hear from my team colleagues. He had meant well though. (Or, management might be rubbish, where i would then focus on supportive friends/colleagues instead). Going back to work can be a hard step but the routine/structure does help.
Sending a hug xx
