Any advice please

Msida you are not an idiot. You are grieving and going through a huge life change. I don't know if you can confide in family/friends at all? If not, would you maybe consider bereavement counselling to help you through this massive life change?

You're certainly no idiot.
You've had an immense loss, and grief can take your mind on many paths.
It's such early days for you, try to be kind to yourself like you would be to a friend.

I wanted to move because of all the bad memories in the house that hung over me

I did like the flat I am in now when I saw it but there were warning signs that I would not be happy but I ignored all those feelings.. I don't know why. I thing I really felt I needed a new start but did not know I would feel this bad, I'm an idiot

Moving house is an emotional event any time. You are still feeling low because of your loss. Give yourself time and go out to look around your new neighbourhood. The local shops and parks and just take the area in. Be kind to yourself with some nice treats for your new home to make it yours.

Oh Msida what a horrible time you are having. I'm so sorry for your loss. Moving at any time is so unsettling but now it must be even harder for you.

Can you talk to family or friends about this as I am sure they will want to help you. Perhaps looking into some bereavement counselling can be so very helpful if you could face that.

I moved house at Christmas and the unfamiliarity and hard work of the whole job knocked me for six. Now, a few months on things are settling down, the flowers I planted are coming up and I feel happier and less worn down by it all, but it has taken a while.

What made you move at such a difficult time? Did you love the new place when you saw it and if so, what's changed since?

Msida, I’m so sorry you’re feeling this way. Without wanting to rub salt into your wound, I think you have 2 big events…..the loss of your husband and then a house move..
Have you met your new neighbours? Why don’t you put a note through their doors , introducing yourself and invite them over for coffee ? If it wasn’t for the restrictions, I would suggest holding a small coffee morning ….. good luck. You’re probably having a bad day. Hope you feel better soon.

You are still grieving the loss of your husband, so so you think perhaps today is 'just' (for want of a better way to put it) a bad day?

I don't know what to do
