Break up of what bro. If you really love someone you will never feel alone or depressed because you just want all happiness for that person without an inch of selfishness but if you are not in love just a relationship you will be depressed and beyond.
About 2 weeks ago my grandpa died due to infection and cancer. My sister was getting about 100 emails and visitors everyday trying to cheer her up while i didn’t have anyone through that tough time, I was just sleeping alone in my bed. My family members and friends didn’t even give me a call. 😢
