I don't know whether it's an anxiety trait or not but not too long ago i went outside and that was after a long period of not being out at all and so i decided to take a long walk but then when i started walking i started feeling like i couldn't take another step. It felt like my whole body froze and went instantly numb. Like at one point i freaked out and started running because i felt this immense amount of fear. I don't even know what i was scared of. It was very similar to what i felt when i had my first panic attack. Like this strange fear that you get that enters your body for no apparent reason at all. I hope someone else can relate because i feel very alone in this and i have never heard other people mention this before.
