I lost my daughter to cancer and honestly, it got worse a few months down the line. There is always a notion of a little better every day, but that's not how grief works (in my experience). It ebbs and flows. Life will never be the same, I find that it has changed now, there was this life before she died and this new life where I feel unsettled and there is a feeling that something is terribly wrong, all the time. There is, my beautiful daughter died.
The "good" news is that this doesn't mean I don't have happiness in my life, that the grief didn't change over time, it did. Did it become easier over the years, yes - but not overnight, it was very gradual.
I had a good support system and a family that has always not been nervous about talking about her casually, they miss her terribly too.
You will be ok, but you are very early on in the grieving process. Please don't give yourself a hard time, allow yourself to feel the loss - it is normal to feel bereaved, you are. It will get easier. 💐💐💐 hugs to you.
