In church and other public situations I've been getting what feels like an uncontrollable adrenaline rush to the neck. It makes my neck kind of shaky. I'm not really sure how to describe it but it's really scaring me. It kind of feels like I'm going to have a seizure or something. I leave the social situation when this happens and try to make it stop and I get all shaky and it's almost hard to breathe. Is this a typical anxiety attack? I've also just been feeling extremely off lately and I can't explain why or how it feels.

I am planning on hiking Halfdome in May with some friends.I would say I'm relatively fit but I'm really scared of heights. I hear Subdome is pretty terrifying. Should I do it? I'm going to feel like a loser if I chicken out.
