Mom Died And Scared to Go Back

Hi everyone, i‘m all set to go back and finish my last 5 courses but I feel petrified. My mom died around 7 months ago and I still wake up everyday not being able to comprehend it. it was sudden stage 4 cancer that took her life 5 months from diagnosis. No funeral, I barely remember what she looked like then because I think I blocked it out. She kept saying she would stay alive to watch me graduate, I took a break but it doesn’t feel long enough. Any comforting words are appreciated. If any Seminoles have gone through this please provide some light.
