Help plese!?

Okay so I've been told by a few doctors now that i have Panci disorder. I have taken medication such as ativan, and it does help. I don't have anymore. For the last few days, all day and up until I fall asleep, usually around 5-6 in the morning...sometimes 4 if i'm lucky (haven't been given a medication that helps me sleep yet) anyways, the problem is I haven't been able to breathe at all properly. I understand the symtoms of my panic attacks, but this breathing issue is quite different. It happens all day, i'm just suffereing from it. So now, it's more like i'm just having one big panic attack all day. This isn't normal for me, because I usually only have panic attacks at night, that's when they occur. Thats why I waas told to only take ativan at night...no more than I need to. I want to go to the doctors, I will make an appointment tomorrow...I was just curious as to know what some of you think. Is it bronchitis? or acute asthma? my boyfriend has it, he says thats what it could be.
