faking symptoms or whatever? idk

So I (19F) have recently been diagnosed with bipolar 2. I found it important to disclose my age because i find it has significant impact on the diagnosis, since so many people only get this diagnosis later on in life.

I am very privileged to have had psychological and psychiatric follow-up since i was thirteen. My diagnosis had always been high functioning depression, however, about a year and a half ago i changed professionals and now am with a new psychologist and psychiatrist, who have met up to discuss my medical status and have come to the conclusion that i am bipolar.

However, I sometimes feel like I made symptoms up or somehow manipulated highly trained and experienced professionals into thinking i have something i don’t have.

Have any of you experienced that?

If so, how did you handle it?
