Processing emotions

I’m having a hard time processing emotions/feelings. I’m feeling very overwhelmed with all my emotions. I try to sit with and breathe through emotions (mostly fear and anxiety) but then it becomes so overwhelming that I feel paralyzed. I am working long hours and waking up in the middle of the night with panic attacks so I’m physically exhausted as well. I spent the weekend trying to rest and recover & was starting to feel better but then everything just came flooding back on Monday. Do you have any suggestions on how to manage and deal with my emotions/feelings?
