I'm seeing my family doctor tomorrow to discuss my anxiety and potentially be referred to a professional. This is my first time doing anything like this and I'm pretty anxious about it.

I went to the ER on Friday because I was thought I was having serious heart or lung issues. They found nothing wrong with me and adviced to see my family doctor to look into doing something about my anxiety.

How should I approach this appointment? How should I discuss the problems I've had with my anxiety? What kind of questions should I ask? 

Any advice is appreciated.
