Hello Mavis,
I'm so sorry to hear about the loss of your husband. It is still very early days for you, so I am not at all surprised to read that you are finding coping with being on your own at home now such a change and so difficult to bear. You are probably still in shock and are in a bit of a daze. I know I was for quite a long while after I lost my mum. That was almost two years ago now and I am slowly getting more accustomed to it, but it is not easy. The house still feels very empty without her in it. I have her pictures around and I still talk to those most days and tell her about my day. It may sound mad, but it seems to help!
I think all you can do at such an early point and while the weather is still good, is get out for walks in the park or sit in the garden, if you have one, and try to absorb and process all that has happened. I found it calming and comforting to spend time sitting in my local park trying to recover a little and work out what I was going to do next. It is a change of life and an unwelcome one, to lose someone so close to you and the effects reach into every corner of your world, so you will have lots to learn to deal with and being in alone is one of them, sadly.
I find it helps to switch on a radio or the TV for background sound and having flowers around helped lift my spirits a little and reminded me that there are still good things in the world. I also spent time collecting some of my favourite photos of my mum and it also helped to keep a journal of how I was feeling and what I was thinking about each day. It helped to write it down and got it out of my system a bit. If you have offers from friends or family to go out for a coffee or something, that can help break up the day a bit too and get you out of the house and it is good to talk to someone, so do try to take up any such offers.
Later on, when you are a little further along this journey, you will find other things to occupy you as you slowly try to pick up the pieces and build a new life for yourself. I joined a class in a subject my mother also enjoyed and found some new friends there and it helped too in that it got me out of the house a couple of times a week and gave me something to look forward to and that made me focus on something other than my loss for a while each week, which did me good. I am sure others will be able to make more useful suggestions too.
I think though, that if you can manage to deal with the everyday chores and remember to eat and drink properly, that will be quite enough at this stage.
Sending you an understanding hug.
