Does a panic disorder feel this way?

This is pretty normal for an anxiety disorder. Obviously I'm no doctor but can tell you about what I know. It's very coon to feel detached from the world, like your going mad and nothing is real, like your in a dream. Do you have any physical symptoms?? For me I get chest pain, short of breath, weird feeling in my throat, muscle tension, fast heart rate, dizziness, the list goes on. If your suffering with this symptoms to them I'm almost 100% sure it's anxiety. 

These are very common symptoms of an anxiety disorder. The brain is seeking an explanation for why the body has gone into the sympathetic nervous system defense mode (fight or flight reflex). It will then come up with every possibility it can think of as to why this is happening ie. I'm about to die, there is something terribly wrong with me, I'm going mad, I have some unsuspected illness etc. in fact, any catastrophic scenario it can come up with because the body is telling it that it is under threat by releasing adrenaline into your bloodstream to protect you (which causes all kinds of strange and uncomfortable sensations including derealisation, rapid heart rate, sweating, shaky legs, over-breathing, muscle tension in the chest and many others). The good news is that there is absolutely nothing wrong with you apart from feeling anxiety. For reassurance it is always a good idea to get checked out by your GP for any physical symptoms but if nothing then it is just anxiety. Nothing will happen to you. It is not a mental illness. You are not going mad. It is your bodys own defense mechanism you are feeling. Horrible, I know, but not actually anything to be worried about as it will do you no harm whatsoever. You are not schizophrenic (I used to think this too), you don't have any of the symptoms.You are perfectly normal. Many hundreds of thousands of people suffer these feelings every day. The way out of it is to get educated about it, which you are doing and then stop running away from the feelings and thoughts that it produces. That sounds scary, doesn't it, but by avoiding, running away from, or trying to get rid of it, you are sending a signal to your body that there really is some danger that needs avoiding . It will then obligingly pump out more adrenaline, causing more upsetting symptoms, then you worry more about what is happening to you, it pumps out more, and so on, round and round. So we get caught in a vicious cycle about nothing becuase there is nothing wrong. The THC in the marijuana wll have left your system months ago so it cannot be affecting you. To recap then. You got a scare from the strange sensations of marijuanna (long gone) which released a bit of adrenaline.  You have then perpetuated the anxiety by dwelling and worrying about it. You are maintaining the fear by believing that there is something terrible happening to you. There isn't. This is the oldest trick in anxiety's book. There really is nothing wrong with you but I agree it is a very convincing illusion. Have a look at other posts on this forum to reassure yourself that you are not the only one and for further info. Good luck and big hug xx  ps. there is information out there that connects excessive and large amounts of marijuanna use with psychotic illness but I should point out to you that you only smoked it once (not enough) and if you were truly psychotic you wouldn't be able to write your very coherent post. Also you would be hearing and seeing things that are not there (which you are not). You are frightened, that's all. It is not a mental illness.

Hi Hun it's pretty normal with some people cannabis is very strong these days and it can trigger anxiety prob best you don't try it again if you take any drug and think your going to die your most likely have a panic attack. I use to suffer with panic attcaks and heart paputations due to my anxiety I found exercise haloed me to chill also it stopped my anxiety... Hope this helps
