A most difficult question. But the puzzle is the harder you try to answer it or the more pressing the need the more frustrating I find it.

So my trick is to check how physically I am and worry about the interior when later.

It doesn't really matter how I am doing - unless I know how I am doing and it is not good and so I need to talk to someone. That is my second trick, to know who to talk to if things get desperate. Find a service that is free and available 24 hours a day and put it in your phone now:)

The third trick is then to go and do things. Something that you have been putting off, something like a daily chore just anything to get moving. Walk around your home, just anything.

Good luck:)

Compare yourself to other situations, if it could be worse then in my opinion you are doing ok. Maybe it's not perfect, maybe it's not fair. If you are well, safe, warm and not hungry you can slowly improve things for yourself.
