Really Confused about When I am in AF

I am a 57yo male recently diagnosed with AF - I say recently although it started 4 months ago and I have been in Resus' 9 times since then with HB up to 193. I am still waiting to see a cardiologist and my GP just keeps saying its only AF and put me on Warfarin. I have done research and understand what AF is and the risks but although I understand it I am not sure when I am in it. Reading these forums many people say I had an episode last year or I have them every 3 months but like I say I have had 9 fast AF episodes in 4 months - is it fast AF people refer to when talking about AF. In addition to fast AF everyday I have Palpitations and Flutters although my HB is low and seems steady - is this AF?  I also have episodes when my HB is low but clearly erractic and also episodes when the heartbeat is erractic and the HB seems to vary from 60-100 beats and is not constant. I have had 16 episodes like this in the last 4 months but is this just an irregular HB or is this also AF?  These episodes are always when I get up in the morning and for some reason all my fast AF episodes have been when getting into bed or within 5 minutes of getting into bed - it seems to be connected with lying down.  The biggest problem for me is dizziness regardless of what my heart rate is and this has led to some distressing incidents when out and about which now makes me anxious about going out and even led to a few panic attacks - of course all these fed's the Af and the AF feeds the anxiety.  Apart from Warfarin on no medication at all - I always self revert from fats AF as well - the longest in took was 2 hours and the quickest 20 minutes. Sorry if my questions seems daft I am just a bit confused by what others actually mean by AF. Thanks.
