So sorry for your terrible loss of your lovely daughter. I lost my youngest son aged 27, aug 23 but it still feels so raw especially on Sundays. (the day we lost him).
All I will say is you are still in the beginning of grief and you must take as long as you need, we are all different. You can’t rush it. I walked my dogs every day and still do and it’s my therapy in nature, walking, Crying, talking out loud to my son and it helps.
Just take it one day at a time, do things when you want to. Try and do things differently if you can, tiny steps is all you can do. I spend a lot of time alone, happily (well probably wrong word), comfortable in my own company, see a few friends when I want, the emotionally intelligent ones, few have been dropped.
Thinking and watching trash tv which is a comfort on the brain.
