I know the feeling..... I also lost my grandma decades ago while I am also taking my final exams and away from her...She's my favorite lola coz she's the one I'm always with specially kapag me sakit ako nung maliit pa ako, she's always with me since I came into this world....she's like my 2nd mother...
Honestly, I am devastated at that time.....but I know I have to move forward and just remember the good wisdom she imparts with me....Now I knew that my grandma and my mom are together in the same place....... sometimes, when I'm alone and reflecting on what I have done with my life so far, I cant help but miss my parents and my grandma....things are a lot better if they are still around.
mbeige, you have to be strong and accept that all your love ones specially older family members will not stay with you forever....... and soon it will be our turn to leave our loved ones, so as for the meantime, whenever you can, make them feel how much you care and show your love to them so that there will be no emptiness inside you if someone whom you love suddenly left...
Take if from me bro....been there and it hurts everytime....
