Does your mood change based on weather and if so how does it change? I spend time both in PA and NJ because of my job. Our winters are cold and our winters are dark compared to the spring and summer. I have noticed recently that even though it is spring, but its been raining and cold outside I have become harder to be around and I am more irritable then when I can go outside for a run and have less access to sunlight. I am in very much need of warmer weather and more sun light so I can be more cheerful and easier to be around.
