I am really pleased to hear that you have those supports in place with your dr and psychologist sessions and medicine. Without these, it could feel even worse than it feels now, so it's a really good start.
Of course it all feels so incredibly hard right now. Even the simplest of tasks probably feel mammoth at the moment: getting out of bed, feeding yourself, getting some exercise. I think this is natural, as pretty much all your familiar routines and structures gave been ripped away from you, all at once no less. This is no small challenge. You are doing well, getting through each day as you are.
I'm really happy to hear you have some good friends to call on and to help you through this time, although they can't be there 24/7.
Being in the house by yourself must feel really strange, it is filled with a decade of memories of you building your family. I think when you move into your new accommodation, it may feel a bit like you can start to move forward or something.
Feeling anchorless is frightening, and as you and B bear have both said, creating for yourself some routines will really help you. I know it feels hard, but it will be worth it.
When you feel at a loss, or if you might dissolve (this is how I've felt in the past when everything familiar has been ripped from under me), can you think of some go-to activities that could help you get through that moment? Reading a book, going for a run, gym, digging in the garden, dancing, playing music.
If all else fails, come to the forums and talk to people who care.
Thinking of you.
