I feel much better when I'm outside in a different city, away from all the crap I've left behind.
I have mixed feelings when its summertime. On one hand, I love being in the sunshine in a t-shirt and jeans. On the other hand, especially around other people and going into shops, I tend to feel myself sweating a lot more and therefore getting anxious, which in turn makes me sweat even more etc....
I've always loved rain and snow. I find it very theraputic listening to rain especially when going to sleep.
