Its such a huge transition isn’t it. And one I will be going through soon as well. I do wish society gave it as much attention as other life changes. I don’t think it’s necessarily easy and what ‘works’ for one person, can be meaningless to the next. For me, no matter what, being out in the fresh air makes me feel a little better. So if you’re feeling lost today, and can manage it at all, I would say go out somewhere, even if it’s for a walk, or maybe to a local park, library, or somewhere for a coffee. Then, maybe expand on that a little each week, and add in something where you can talk to others -a group perhaps-and try out a couple of activities-it doesn’t matter if they turn out not to be for you. Try to plan a little something for each day either by going out, or trying something new at home, and I think when you get in your stride, you will gradually have started to build a life for yourself. Good luck!
