I can relate. I find having a list helps me, I like being able to cross off each chore when it is done. I break each chore down into stages, for example I'll sort out the washing. Next time I get up for a glass of water I will pack the machine and turn it on. Next step is hanging it out, then lastly bringing it in and folding it. This might take me all morning but its one thing off the list! I also do as much as possible while I am on my feet, everytime I get up to go to the loo or get a drink I will do a little bit. It can be overwheming but little by little you'll get it done
