Yes, when we are in a very anxious/depressed state the slightest thing can cause a retreat to our cave. It is definitely part of the illness. Do you keep a journal? It may be helpful to note down the things you have achieved, however small (eg making a cup of tea) Self-compassion is something that is initially hard because we are often so critical of ourselves. It is important to be kind, giving ourselves small treats. If you haven’t come across Dr Cantopher’s book ‘Depressive illness:Curse of the Strong’ it may be worth a look, it was a turning point for me.
