Hi,
Background: I worked right up to 40w pregnant to ensure a smooth handover and to train my replacement (I had the new start for a whole week, despite work knowing from 12w)
Male dominated environment. Public sector. I HATE IT. The job stresses me out. Line management are nice men but put a lot on me and I cry at home a lot. I have a transfer request in but these things can take a long time - years, maybe
New start tormented me with work related questions when baby was born - that tailed off, thankfully
Colleagues - same grade/lower - have liked occasional FB posts
Direct line manager sent me one message on the day baby was born to congratulate me. I haven't heard a word from him since.
I emailed HR in line with policy, to inform them I'd be returning to work in x weeks time. I cc'd in both my direct line manager and his (normal procedure), I then sent a text message to their work mobile phones - again, we would regularly text to communicate on work related stuff - and said:
Hi, I hope you are well. I have sent an email to HR re: return to work. I plan to come back on x date. Please give me a call to discuss. Speak soon
It's been a week. Both are working, sending emails and communicating with other staff members..*

My anxiety is through the roof. I've cried so much at the prospect of going back anyway, but now I am thoroughly dreading it. I feel miserable and now I'm so upset because I should be spending this time enjoying my baby and I feel like I'm spiralling. I have to go back to work, leaving isn't an option 
At what stage WIBU to contact welfare? Are they out of order for not contacting me? What do I do?
