Hello, I'd like to help you with your question.
In order to help you heal from what you went through as a child coping with a mentally ill parent, you need to see a therapist who can help you understand what happened to you as a child compared to what should have happened to you as a child. A therapist with a good understanding of childhood development and/or a therapist who understands how the past affects your present emotional state is a good choice.
The type of therapists that can help you include:Psychodynamic
- These are therapists that are Freudian but are more modern in their approach.
Gestalt- Therapists that work with the impact of your past on your current situation and help you reframe your emotions.
Humanistic- Which studies the whole person in therapy.
You can also try on line forums and support groups as well as books to help you find others who relate to your situation and to understand your situation better. Although NAMI is the standard source, you can also find smaller organizations that help. Here are some resources and links to help:
My Parents' Keeper: Adult Children of the Emotionally Ill by Eva Brown
Surviving a Borderline Parent: How to Heal Your Childhood Wounds and Build Trust, Boundaries, and Self-Esteem by Kimberlee Roth, Freda B. Friedman and Randi Kreger (I'm not sure what your parent is diagnosed with but this may apply and help anyway)
Life After Trauma, Second Edition: A Workbook for Healing by Dena Rosenbloom PhD and Mary Beth Williams PhD

I hope this has helped you,
