What should i do? (9)

I had a friend who had left the school she was the only person that understood me we met each other as aides of the library and we were always there alone me and her would talk about our life struggles and she also was getting bullied same with me and we both hated the school then i eventually had a crush on her but i never could tell her every time i said today my mind said tomorrow and now we never really talk anymore but we still do every once in a while and shes the one person who makes my life worth living but my question is should i tell her how i feel.
