I'm new here and I have experienced panic attacks throughout my life but within the last few days they have hit me extra hard. And they might happen for several hours and then stop only to return the next morning. In between these attacks I will have moments of great calm and no worries at all. I'm wondering if this is more than "a coming and going of panic", or is it more of a manic/bipolar thing. It got bad enough that I wouldn't leave the house. If anyone has advice I would appreciate it. Thanks.
