I'm tired of studying, I can't focus on studying, it really started happening recently especially I always feel that life is so empty even though we are working hard. I think this is the reason why I feel this way. I feel that as I grow up, we are slowly drifting away from our family, I can't bear it, I can't face that reality, I remember the past. It is difficult for me to do my studies with these thoughts, what should I do?
