Hello Dawn; so sorry you have lost your mum and it must be difficult for you coming up to the first anniversary of her death.  I am attaching a link from this website about grieving which might be helpful.  But there are no hard and fast rules for grieving; everyone has their own way of doing this.  Sometimesx it doesn't hit for a while; sometimes you think you are getting over it but it comes back and bites you from time to time.  But it is generally reckoned to be important to let yourself grieve.

I was not somebody who cried much; I used to talk about and to my mum after she died; I kept a few of her belongings and things she had given to me and sat and talked to her while looking at them.

Come back and talk again if you would like to do so.  Annie
