feel sad and tired

I had an unhappy incident today at work. One of my colleagues, Xuan Min, when talking to me, raised his voice but he talked to others nicely. I really hated him because somehow he reminded me of my past. At that time, I really like crying. Plus, my grandfather had been deteriorating. His doctor say he might have to go for an operation but my family members objected to it because they think that he was too old for it. But frankly speaking, i think that he should go for the operation. At least, there is a 50-50 chances that he dont have to keep going to hospital to stay. Sometimes, i really feel very useless because it seems to me that my EQ is not as high as last time. I am emotionally and physically strained but life still have to continue
