Condolences on your loss.
I'm sorry for your loss. I lost my mother 2 & half yrs. ago. There's really no loss like it. You will have to get use to a new "normal". It gets somewhat better with acceptance over time but you never really get over it. It's a strange new reality that you start to live within, somewhat akin to feeling like you've become an orphan. I wish you peace in the midst of your sadness and hope you have many fond memories of your mother to sustain you going forward. Just don't let anyone tell you to get over it and "move on". Move on at your own pace, which is a pace that varies from one person to another. Take care.
