I actually didn't realize I was good at faking it until my T was talking to her team about my case trying to get some insight when one of my DBT group leaders was like "really? She gets along with everyone and jokes around all the time! I didn't know she was dealing with all that!" My T told me that I needed to find my voice and stop putting up a front. I was like what am I supposed to do? Walk around crying and being sad all the time? I only put up a front because I had this notion that I had to act okay after my mom died. It took years of practice. I don't have a straight forward answer for you, but if your friends are avoiding you because of your depression, maybe their not the good friends that you thought they were.
