I had a really bad panic attack last night and as a result, I couldn't sleep no matter what I tried. Everything happened all of a sudden when I was going to sleep. I’ve never been more scared in my life. I felt like I was living in a dream and that nothing was real. My heart was beating fast and I felt random anxiety as well as somewhat shortness of breath. I even took prescribes to help me sleep, but no luck. After finally going to sleep with many many efforts, I woke up and have felt very off. Still the same feeling as yesterday, heart beating fast, and anxious. As of typing this right now, I feel horrible. I’m so scared this won’t go away. I feel like I’m losing it. I have a history  of depression and anxiety but this is a new, horrifying feeling. Should I go to a therapist, or will it go away on its own?
