Family Night?

My mum has asked if I'm going to cancel Family Night this week. She says she can see I'm not well enough and that is true, but I feel guilty about cancelling so often.

To be honest, my function is way down. A short walk between bedroom, kitchen and bathroom leaves me nauseous with a racing heartbeat and with quivering, shaky muscles. I can't cook for myself or do any real shopping or clean the house. When I bath, I can wash my hair but have no strength to dry it, let alone style it. I have had a couple of days in bed and it has done a bit of good but I'm still far from the level of function I would like to be at. I'm tired but sleeping well. The tiredness is not so much an issue as the nausea and weakness.

At times like this, I can't believe I will ever feel well and function well again.
In fact, I'm not too sure I remember what that feels like.
