I just can't face going out in a fruitless attempt to buy presents for 3 people. The only 3 in my life that I will really feel guilty about if I don't. My DH, my DM and my step-dad. For context, DM is a frail 89 year old and this could well be her last Christmas. I haven't seen her for 3 months due to being ill (colds and bad cough) as well as feeling particularly antisocial.
I know I suffer from SAD. My DM knows absolutely nothing about my health and wouldn't understand if I told her I'm often too depressed to leave the house. Step-dad probably just thinks I can't be bothered.
How can I reconcile my feelings of being useless with the feeling that I should be trying to make an effort?
