Wow this sounds very stressfull for you. If this is what happened why isnt your daughter with you though? Just beacuse youve had a break down doesnt mean she has to stay with her father. There is plenty of people who have breakdowns, mental health issues and still have children within there care, was it the social services that took her from you and gave her to dad? and you speak about your ex and his girlfriend, how is she with your daughter do you guys speak?
