I'm a really serious person, but thinking about my grandmother made me cry.
Why did thinking of your grandma make you cry?
I don't usually cry, but I miss her so much.
I know how hard it is to not see your grandmother. It's okay to feel emotional when you think about your family and not being able to spend time with them. It will help you get through your grief to let your emotions out.
I wish I could have had more time with her.
I am sorry for your loss and your relationship with your grandma sounds quite sincere. You should let out your feelings and visit her grave. Leave some flowers and just talk to her to express your sorrow.
