Yep, the specialists having interviews with multiple different people from your environment (friends, partners, siblings...) help a lot to differentiate what's real and what not. Also, it's usual that once you pass your twenties you stop living with your parents and/or start shielding them a bit of your struggles, so they don't have the full view of your day to day "fight".

In my case they had interviews with two exes (who are two of my best friends), my sister and my parents.
