It sounds like depression talking, friend.
I am in a similar situation and it's tough!
Do you have people around you?
Anyone to be a walking buddy with you?
Can you join a gym and get yourself to go?
I find having someone around helps me to do more. Also, making plans with another person motivates me some of the time.
Have you seen a pdoc for a medication review?
I am very depressed and have found stimulants very helpful.
I hope you find some answers.
Keep posting!
