Welcome to the forums @Individualperson.
The first thing I would suggest is to look into options for a therapist. They can help you talk through your experience and start to see how to take the next important steps. You could also try looking for a DBT workbook online.
You should also take a moment to acknowledge that you've already taken the first step to recovering, by reaching out for help online. That can be a big step, but you made it.
