I was getting extremely stressed taking care of my dad, I was trying to do everything as well as keep control of him (which was nigh on impossible). It took me breaking my wrist and not being able to drive to take a step back and look at the situation with new eyes. I realised that dad could still cope on his own (yes I didn't like what he was doing) but to him it didn't matter. He might not have been eating at the right time or the right food, but he was eating, he also wasn't changing his clothes or washing as much as I would have liked him to, but that also didn't matter. For 8 weeks I had to satisfy myself with only seeing him 3 times a week, he survived and to be honest he was none the wiser that anything was different.
When my wrist was better, I decided to just go with the flow and not let the little things bother me and turn into big things, I stopped planning and trying to control everything (I am a terrible control freak). So instead I would take a deep breath and just accept that it was just how things are.
I also joined a leisure centre and started going swimming and the gym (in order to help my wrist gain strength and de-stress, Dr's suggestion) Making that time for me early in the morning, before going to visit dad, really helped me. I also have some very good friends who were very supportive and were happy to lend an ear.
