Sam, your mother loved you and you loved her too, she fought but she needed peace.
Don't blame yourself, I did that for years after my father's death and it did a lot of damage, the time I could have been using to remember him, I spent it hating myself.
It is okay to be angry, sad, everything, let your emotions flow, and know that I am here if you ever need to talk, remember I told you that days back.
You will be fine, you will be fine.
Thank you.
You are welcome.
