Try to set aside a day or even a half-day for yourself, every so often. This is time you do all the things that you enjoy, and put aside all the things that you should be doing.
If you feel like it, lie on the sofa and read an escapist book or watch entertaining films. I eat a whole packet of chocolate digestives, and drink chai latte because they comfort me. I burn scented oil on my oil burner to help me relax.
I try to do this on a fairly regular basis, especially when I have spent a few days tackling the things that make me anxious or frightened. It is a reward for doing things that I find difficult, an incentive to carry on with the good work and a welcome break from the constant struggle that is everyday life. As I suffer from very low self-esteem, by doing this I am reminding myself that I am deserving.
I also try to do something every day that I like, even if it is only for ten minutes.
