Mobbing at work, what should I do?

[GiselleTorpedo]

Hello lovely ladies,
I am in a bit of a situation and would love to hear what you guys think?
I have been employed with this huge organisation for nearly 3 years now and just returned from Mat Leave a few months ago.
Since then my manager has been a living nightmare. He has been making comments, threats and just overall being really frustrated with me that I have to A) leave on time and B) don't just live for his team (so he can get far in the company). This would include working long hours as well as weekends. There is much more to it but I wont go into more detail as it might be tmi.
The situation has gotten so bad that I started having anxiety attacks in the middle of the night. My heart would pound and I feel sick and dizzy in the middle of the night. I am dreading going to work and I am all choked up every morning. It has been a living nightmare. When I started having non menstrual bleeding I knew its too much to handle so I decided to go to my GP to ask for advice. She has instantly signed me off sick saying I suffer from extreme stress that is caused by my manager and that I shall use the time to find another job.
I was also told that I should sue the the company because under no circumstances they should treat you like this as a Mother. I am now seriously considering speaking to a No Win No Fee Solicitor but I am also worried as this is a huge bank, they must have the best lawyers right?
I am so stressed and dont really know how to get out of this mess, I dont ever want to go back there, but how do I get out of this with feeling better? Because if I just leave without saying a word it will look as if I am in the wrong but I want him to learn his lesson.
I would love to hear the opinion of ladies who have been in similar situations or have some sort of advice? Do I go silently or do I make noise?
Thanks xxx

"When my child was unwell he texted me saying I still need to work remotely as I have a job to do and that it is my responsibility to find someone who can look after my child regardless of her health.
None within my team has kids including my manager so I feel they don’t understand that you can’t just leave your kid somewhere and work "

Again, this will be a context thing. If you've asked for an emergency carer's day of unpaid leave, and acknowledged how inconvenient it is for your manager, and offered to do x,y, z that you can do from home, albeit not your full role, that's one thing. Or if you've phoned and said "Arrgh Isobel is really sick, I can get someone to care for her from tomorrow, but today is impossible, can I take a day's annual leave please?", then fair enough, also. But if you have taken the view that 'my child is ill, there is nothing I can do, I just have to be home with them....', that's not going to fly.

It probably just hadn't come across in the usual way that forum posts sometimes do, but it does seem that you have gone back to work and reduced down to a bare minimum, then been surprised that your manager is unhappy.
