What should i do about my depression and hiding my feelings from everyone?

Find a therapist: A skilled therapist will be able to help you figure out the answers to these questions.

You are not alone: You have taken an important step-acknowledging to yourself that your depression & "cover-up" response to it are a problem. If you're embarrassed to get help, remember that you are not alone. Quite likely, some of the people you are hiding your feelings from, are hiding the same feelings from you! ask someone you trust for a referral, or check for an eap program at work. You deserve to feel better!
