I thought panic/anxiety attacks were bullshit too. I lost control of my company about 16 mos. ago and got booted out of my own business.
I siloed and compartmentalized the stuff, mainly to insulate the family and friends from everything. I fought depression and stopped lifting for a year.
I started having racing heart, tightness of chest, etc. I went to the ER thinking I was having a heart attack and wound up in the doctor's office several other times for EKGs. There was nothing physically wrong with me.
I refused to admit that I was having these problems, but in the end, it was repressing all of the past years problems and pending worries.
Don't listen to the crap about it all being BS. It is in your head, but your head controls your body and the symptoms can be real.
Go to a therapist or get some other outlet to go be honest and talk through some of the shit. I am NOT the touchy-feely sensitive type at all. But, I can tell you, when I am looking at my 9mm thinking about popping a round in my head, everything becomes real.
Be careful on the Xanax/Ativan/Valium etc...its easy to become addicted or very tolerant to. But, when you need one, you need one.
Good luck bro...
