You sound quite similar to my exH
We've been split over 2 years and DC. He has MH problems and actually so have I. We both felt like we were walking on eggshells and said as much at different times.
Firstly - has she actually stopped contact? Or are there barriers to contact that you can overcome?
My exH isn't prepared to have contact supervised after displaying behaviour that professionals advised me required supervision initially
My exH is simply not prepared to do anything that was required of him to see his DC
His MH is a contributing factor for behaviour but doesn't excuse it or stop the impact on DC or myself as an ex partner but then wife
There might be nothing you can do or know of... or something you can do and know of that will prove you will put your DC emotional and physical wellbeing first - whether that is treatment, supervised contact etc ?
Are there factors in your own life where you are expecting children to simply understand and support you rather than you prioritise their needs?
You say you are trying to put your life back together but took a month off... try to see that from the perspective of a child and the mother who then has to support that child through a month where their father was unable or unwilling to continue contact
I understand MH is an illness and can't be helped, but yours has impacted so severely that you couldn't parent for a month. If the mother had also been in this position- she would have had to give up her children... and then fight to have them returned when well... and the children would have had the trauma of the separation
And lastly, are you being completely honest about MH diagnosis with yourself... don't worry about telling us but some illnesses do have symptoms that may lead to a greater concern if evident - suicide attempts while can be from depression and anxiety suggest it is a very severe form if that is the only diagnosis
I hope you get the support you need and hope you are able to see through hurt from your ex wife to why she may be taking the action she is, and what you can do to be a part of your DC life and remedy those concerns with her and professionals. Your DC will thank you in the long run if you can!
