If you are in depression then it will be very difficult for you to keep up with day to day things. You probably want to stay in bed and forget that things need to get done.
Forgetting does not really work and soon you will be attacked with anxiety on top of the depression. The combination of the anxiety and depression can be torturous.
So, you have to forgive yourself for not being able to get everything done, and scale down the tasks to the minimum. Just do the most critical things and break them up into smaller bits and pieces. Some things require several steps, so you can write out the steps and then do one today.
I know what it feels like to just want to leave everything undone and crawl back into bed. You may only be able to do 15 minutes or 30 minutes at a time. If it is only 10 minutes then that is the way it is today.
People will probably complain to you because they do not understand. Sadly that is something that most people with mental illness have to endure, on top of the suffering we are experiencing.
Everything does not have to be done at once, or back to back. Take breaks in between to do something therapeutic for yourself.
You have to be your own nurse, parent, nutritionist and physical therapist.
Try to eat a little out of each food group. If you can’t then perhaps try Ensure or Boost drinks. It is important to keep your strength up with vitamins.
Get some exercise even if it is sitting on the floor and doing stretches. The limited mobility will make your muscles stiff and uncomfortable.
Write a list of things and then taper it down to just very necessary things. Do them one at a time and take care of yourself in between.
Depression is a real illness. It is just as real as any other disease or illness.
Take care of yourself. Try to get a bit of sunshine. It will help regulate your your sleep / wake cycles. This will combat insomnia.
