Lost track of reality during panic attack/mood swing?

I get really anxious. Like I am fearful of my reality because I don't know what's real and what's not. Like all my experiences, all my knowledge, and all the information I know could be false (this usually happens after something I thought was true turns out to be false) and I just have a huge panic attack along with identity crisis and sometimes I fall into depression for a bit as well.

I try to be rational but the fact is my framework for thinking also alters with my mood so its like every information I process have to go through this lens called my emotions, and thus I can't remain objective or even think clearly, no matter how hard I try.

I just feel super confused, and to be honest kind of afraid as well, in those moment. Does anyone get this? Anyone know why?
