I have suffered with PTSD, Panic disorder, and GAD for 4 years now.
My first attack hit me while driving on the interstate. It was triggered due to a very bad relationship, as was my PTSD. My first attack felt much like a stroke would be I imagine, as my left side of my face went numb and I felt like I was about to pass out. I called 911 and an ambulance came and EMT's checked me out. They said my BP was elevated but everything else was good. They told me to get checked out anyways so I did. Went to Parkwest in Knoxville, as it's one of the best cardiovascular facilities around. They said everything was normal, but of course I wasn't convinced. Anxiety does this to you. You still believe in the worst.
The next few years were absolutely debilitating. Random attacks for no apparent reason, mostly in my sleep. I had several ER visits, which did nothing but rack up a bill. I finally accepted I had a mental issue going on, so I started going to therapy. It helped tremendously, but I was still having attacks, just not nearly as often.
Today I'm glad to say much of this is behind me. I still get odd feelings of anxiety at times, but it's been several months since I've had a full blown attack. I recently cleaned up my diet, going to a Ketogenic lifestyle, and believe it or not, low carbing has had a big impact on my mental health. I feel much more clear headed and don't have that constant dizziness that anxiety presented much of the time.
Anxiety is very debilitating and I feel for anyone who goes through it.
I also would like to add that since being back on vitamin d, myood has stabilized too. I do think there is a correlation between vitamin d and anxiety. Same goes with testosterone. My levels tanked again to 245 recently and I started getting the anxiety again. Its amazing what the body does.
