If I lost all of my possessions, I don’t think I’d have a choice but to to get on with it and start rebuilding my life straight away.

I could be angry and upset, but that’s just wasting energy. If life is tough for any reason, your efforts must be directed towards improving that situation, including if all possessions are lost in some way. Day by day, doing something to improve life in a positive way would get me back to where I would want and need to be.
