A lot of it is historical, so you might want to skip to the sections on treatments like EMDR. The author shows how nightmares are the brains attempts to process what happened and has suggestions for moving past them. While Bessel van der Kolk practices in the USA, perhaps you could contact him (or the group he works through) and see if he or they can suggest an informed and compassionate practitioner in your country?

"Out of the Nightmare: Recovery from Depression and Suicidal Pain" by David Conroy
A key point David Conroy makes is that all too often when people reach out for help with pain exceeding their coping resources (and so leading to suicidal thoughts) that the people they turn may just heap more pain on top of everything, which sounds like what happened to you. But it does not always have to been like that and David Conroy explores alternatives in his book.
And you might also want to look into "The Lifestyle Cure" which has a fairly high cure rate for depression using a combination of omega-3s, sunlight & vitamin D, exercise, social interactions, mental habits to avoid negative ruminations, and improved sleep: https://tlc.ku.edu/
But if it is past trauma that is causing the worst issues, addressing that first might help get you on an upward spiral and then you could try those other ideas to continue towards greater wellness. Hope this helps.
For anyone who has struggled with depression or severe anxiety, if you haven’t read the book The Body Keeps the Score by Bessel van der Kolk, I encourage you to read it as soon as possible — it’s one of the best, most approachable, resources out there to understand not only many of the roots of depression, but many strategies to actually overcome it (it’s very different from traditional talk therapy, which is mostly focused on getting people to cope with their past trauma rather than resolve it).
