Honeydew is never, ever ripe. Same can be said for most cantaloupes.
When I had my panic attacks I found that walking helped. It made me move and focus on my walking and looking at my feet or the scenery around me was a good distraction. Walking did make my heart speed up a bit more but walking toward a destination took my mind off the attack somewhat and I believe it helped me get over my attacks quicker than if I had stayed sedentary. I also found out that coffee, cinnamon and RX protein bars triggered my attacks.
