Panic Attacks?

I have suffered with anxiety and depression for many years. I do get panic attacks and they are terrible. I usually get them when I feel like a situation is out of control. When I feel them coming on I try to go for a walk. I find that helps me. If I am unable to go for a walk I do my best to breath my way through them. I am not on any medications for it. I just try to manage them naturally which can be trying at times. I can go months without having an attack but then I can have them often once they start. I have even woke up in the middle of the night having a panic attack. I usually can't go back to bed after one.
