@NatureLover  I'm a checker.  Did I leave the iron on? No! I checked X times! Along with every single other light switch and power point 🙁 
So getting numbers down lower first you see... then baby steps maybe go for a short walk and not have the house in danger. 

It also helped me with the decluttering to give to charities.  I like helping others so for me putting the item into the salvos bin was me helping someone else not me parting with something so much.  Mind games that help.  You need to find what works for you.  
A big help for me with my extra stuff was an animal rescue charity came to my garage sale and made an offer to take everything.  My mind was panicking but because I knew they could sell it all and make a difference for a lot of animals I agreed really fast before I could think about it.  Otherwise maybe things might have started creeping back in my home if the things had hung around.
