Crying all day

Nothing bad has happened... Not to me... But every one else. All these events in the news, my neighbour going to hospital, I thought he was missing for two days, even called the police. My dads borderline homeless, my mum's relationship problems and debt. Suicidal sounding friends. Just everyone around me all have troubles of their own and I try to foolishly help everyone. Today I've decided to stop, it's ruining me... This has been the best year of my life so far... But I still feel like crying.
