The good news is that it will change. Whether that its because of something you choose or something that happens we will turn it into a positive cycle again.
That is very true. Change will always happen, it might get worse, it might get better... but change will still happen.
I have gone for a couple of walks since this post (with a camera and headphones), and the alone time and fresh air has helped.
Just have to try and keep positive I guess...
