If you are looking for a professional who can provide guidance on confidential matters, you might consider consulting an "attorney" or a "lawyer." Attorneys are bound by client-attorney privilege, which means they are legally obligated to keep the information you share with them confidential. However, it's essential to verify the specific laws and regulations in your jurisdiction to understand the extent of confidentiality that applies in your case.
I'm sorry for any confusion earlier. If you're seeking someone to whom you can safely entrust confidential information, you might consider consulting a "confidant" or a "trusted advisor." These individuals can offer a non-judgmental ear and provide valuable insight or advice while maintaining discretion and confidentiality. However, it's crucial to ensure that the person you choose is reliable and trustworthy before sharing sensitive information.
