Sorry if not right flair

I have panic attacks. But a family member of mine (out of nowhere) started acting weird, laid down on their bed, and were apparently crying. 

I’ve never personally cried when I’ve had panic attacks. But I can hear them now and it sounds like they are short of breath or hyperventilating or something. I just don’t know what to do and what this is. They wouldn’t talk to me or tell me what’s going on, besides basically “I’m going to bed, please leave”
