In my experience people recover because of life changes, not therapy.
Therapy is one tool to shed light on things and get advice, as well as have someone to talk to if you have no one else, though I've found that trustworthy friends are more helpful, IF the therapist is actually competent and understands what you're going through and what you need, more often you'd have to go to a psychologist rather than a psychiatrist for that, and make sure they have good knowledge of complex trauma, which unfortunately is rare.
What I've found to be truly healing is substantial bonds, that's number one, no replacement possible, having people who care and are there for you makes you exist and gives you a place in the world. Nothing else can take the place of that, not your mind, not spiritual enlightenment, not nature, not therapy, really nothing. Love and fulfilling relationships are our number one nourishment and condition to flourish and feel secure, it's directly linked to our life expectancy and susceptibility to disease.
Then spending time in nature, at the very least outside in the sun, in a park, or at a cafe's terrace and feeling the connection to the natural world is also a key way to reconnect with ourselves and feel how we belong to a greater interconnected whole.
Working on understanding and helping yourself with free online resources, books, seminars / conferences and just conversations sometimes is also very helpful and can make you understand even more than therapy would, plus learning a lot about the world, what we're influenced by, how we work, the hidden stuff only few people talk about etc.
Having a fulfilling environment to live and work in is another key factor. A healthy, aligned, well balanced lifestyle in harmony with our original nature is linked to that.
Then there's your sense of purpose, what we want to make out of our human experience, our dreams, goals and deep aspirations in relation to making a positive impact on the people around us, and by extension the world. And our spiritual experience.
The issue I've found for people like us is usually that there are obstacles to these fundamental and necessary things and so far I haven't found people who actually researched how to overcome said, often invisible, obstacles, but I keep searching for it anyway and working on all of these areas to the best of your ability helps regardless, so I can only hope it eventually leads to a breakthrough if one believes and persists enough...
