I struggled mightily in college with panic attacks. It is tough maintaining studies when you feel you're gonna croak from a heart attack or wig out in class....I know:) But, we don't die from panic attacks....never do - never will. Way back when, I took Klonopin, for a period, to help with the panic attacks....after not being able to keep things under control by myself. This was about 30 years ago or so and I'm still here:) And, I've had the panic attacks under control for many, many years.....but I still struggle, to my own extents, with Health Anxiety. Anxiety does not dominate me, though, anymore....which is wonderful. Learning how to live with anxiety / panic can be a bumpy road. But, this is exactly what we have to do....we have to learn how to accept it, embrace the things that can help, learn to manage it, learn how to live so very well despite it:)
It's tough giving medicine advise....everyone reacts differently and has their own viewpoints. But, there are some meds that might help with the panic portion (panic attacks) in addition to your Lexpro. I'm not advocating them, but they have help peeps. Also, for the longer-term management of panic, there are many techniques, actions, habits and mindsets that can become a natural part of your overall healing path. If meds are involved, I would view them as a shorter-term 'necessity', perhaps, IMHO, and strive to, eventually, move away from meds and use the other techniques and actions and mindsets that have been shown to help drive a viable, lasting healing path. Just my two cents:)
Do you see a professional for your anxiety? Who prescribes your Lexapro? Have you read any anxiety books? Do you exercise? Do you have any other anti-anxiety techniques?
How old are you?
There is definitely help for anxiety / panic issues. Don't despair. It can be tough sleddin', but there is a healing path for us:)
Peace and Feel Well:)
