Several violations of the code of ethics have occurred, and resulted in significant damage. Actions include wrongful termination, unlawful breaches of confidentiality and much more.

Option 1 – contacting her licensing organization directly:
Advantages: I have full control over the letter and can express better my feelings and thoughts

Option 2 – having a lawyer contact her organization
Advantages: more professional; better chance of ruling in my favor (?)
Disadvantages : she has more money than me and this can be an advantage for her, it turns into an open conflict which might prevent us from reaching the truth, more strangers access my private files, (?)

What do you think is best?
My goals: finding out if I was treated wrongly (very likely), finding out the reason for her (in my opinion unethical) actions, justice, punishement.
