I've been having panic attacks probably for about 6-7 months now. Sometimes on a daily basis. They can be triggered literally by the thought of realising one day that I'm going to die. I had a really intense fear of death as a kid to the point I was scared to sleep with the light off. I grew out of it for years but it seems to be developing back. It started roughly when I stopped smoking marijuana which is the most surprising. I've spoken to doctors and therapists and friends and of course nobody really has a solution for it because they're isn't one. My last doctor's words were "Your right that is a tough one".

Now if I ever smoke weed they trigger no matter what. If I'm in a dark room on my own or in complete silence with my thoughts one will trigger. For example when I have my VR headset on or when I go to sleep and turn the TV off. 

I have no idea what to do but I can feel the stress on my heart and it's definately not good for it. I've started the gym to try and be a bit healthier too. 

What can I do, does anyone have any advice? 

Thanks in advance.
