Therapy, drugs, exercise, meditation, eating well, yoga, whatever you choose to do, remember: all of these things take TIME. Unfortunately.
I experienced my first panic attack almost a year ago to the day. And while I have not had an actual panic attack for quite some time now, it has taken my body a long, long time to get back to "normal." I would say that just now, a year later, things are starting to look familiar like they did before I experienced all my anxiety. That's a year of weekly counseling, eight months of anti-anxiety meds, two nutritionists, a life coach, a chiropractor and A LOT of crying and prayers and emotional support.
And that's the almost beautiful thing about this process. It's more than just about "how can I get rid of this health anxiety so that I can feel 'normal?'" I've started to see it as an opportunity to grow, to see that my HA is a mask for a lot of things in my life that I'm not happy about, or deep-seated issues that now, finally, I've admitted that I need to work through. It's a chance to get healthier, in both body and mind, and to create a new "normal." A better normal. Sure, life's not perfect, but I find that I have an overall better outlook on life; I'm more focused on the things I want to accomplish and less worried all the time.
So, we all understand the fear and the sadness and the loneliness that you're experiencing. We've ALL been there. I encourage you to embrace those things and push through them. Let this time of getting on top of your anxiety be a time of self discovery. It might not "feel" great in the moment, but trust me, slogging through those hard moments can lead to a much better way of life.
Much encouragement to you.
