Grief and breakup.

I lost my grandfather 5 months back. He was equivalent to my dad. I haven't cried. I haven't smiled ever since. It's like a part of me is dead.added to that my boyfriend confessed me he cheated on me few months back . Like i don't know how to react. All the people I loved left. I am not able to eat, sleep. Am just working untill I forget . But it's like a sharp pain sometimes that everything is collapsing. Help me.
