I try to live a healthy lifestyle for the most part. Sometimes it helps my anxiety, sometimes it doesn't. I was born with a heart condition, and was diagnosed with a rare auto-immune disease two years ago. I had also found out that a lot of the food I thought was healthy was actually hurting me. I'm allergic to wheat (actual wheat, not the gluten aspect), soy and nuts. I had been replacing dairy with soy/almond milk, turned out that was making me really sick. I also have arthritis which is a genetic thing for me, so I can't eat a lot of sugar or I physically hurt the next day.
My husband and I are pretty active though and I've always been. I used to play sports, now I just go jogging and hiking with my dogs. I've noticed that if I haven't been out running in a while, I feel more anxious. Which I liken it to how my border collie/lab mix behaves. When he's been out running with me, or we've taken him on long hikes, he's much more pleasant to be around. When it's been busy, he's a hyper/over anxious little pup.
Overall though, I know I feel better when I'm taking care of myself physically. If I have a week where I'm being lazy, I feel sluggish and crappy and my anxiety and over-worrying peaks.
