Hi, my mom was in the hospital and I had a bad panic attack from 10 to 2pm- felt like I was going crazy. My mom died and I had a panic attack after my sister left town. My mom used to be the only one I could talk to about panic attacks and now I don,t have her. The only difference between the new panic attacks is i don,t hyperventilate. I used to hyoerventilate every time I had a panic attack, but now I don,t. Anyone have any advice.
