It was nice to speak with you. I am very sorry to hear about the difficulties that you are having with your ex.
As discussed to seek to get legal aid take these letters to your GP. Explain the difficulties you are going through. Your GP can complete either letter and when they do take it to a legal aid solicitor in your area:
Here are some legal aid solicitors in your area:

Do let me know if I can help you further
I wish you all the best
