Have had a day when I really didn't want to do anything,have only managed to have a shower, feeling guilty, does anyone else have days like that, feeling depressed & sad

Fatigue comes with having COPD and the advice about pacing yourself is absolutely spot on but ... this can be easier said than done. Despite knowing better, I over did things today. Over the weekend I had narrowly escaped a full blown exacerbation and the Respiratory Nurse advised me to start on my rescue pack which I did. Today, Monday I was feeling much better and grateful to be breathing pretty much normally again. So foolishly, I had a shower, and decided to attend pulmonary rehab class to make up for the sessions I missed when I was feeling poorly. Now, I'm flat out laying on the sofa and wondering how on earth I'm going to drag myself up to bed, tonight! Silly me! Are you disciplined about pacing yourself?
