Whats wrong with me ?

Since the last 10yrs of my life I have this peculiar habit

I read/watch reports that deal with human suffering in all my spare time.From the atrocities of Romans against Germanic tribes to British mistreatment of Irish to Famine of Bengal.I have read them all.I do not enjoy this in anyway, infact I get really down after reading all this and sometimes try to imagine the suffering of these people and makes me cry.I'm very sensitive and perceptive to human suffering esp in distant history before we had the benefits of red cross, antidepressents , aid programs.Just cannot imagine how people coped with it.This is a problem though , I spend nearly all my spare time on it.
Its to the point that I don't really enjoy even spending time with my family.I have no reason to be depressed, I have a son, great fiancé, good job and loving siblings.I'm not an introvert have friends of all kinds.Yet when friends and family whine about little things I get really annoyed and give them some perspective by asking them to read about the famines,genocides, etc of the past.I don't say it all the time but THINK about this all the time, so much so that I HAVE NO EMPATHY for people around me as no one is facing extreme hardship and basically tell them to suck It up.

I'm really concerned about this issue as I waste a lot of time reading about human suffering and then feeling sorry for these people and this is affecting work and social life.

We are not professionals here to give you a diagnosis, but something that comes to my mind is OCD -- may I suggest you read about that and see if it fits you? OCD doesn't have to be all about washing one's hands, I thought so until I meet an actual person suffering from it. I might be completely wrong about this though.

As for depression, a lot of people don't have a reason to be depressed. My favourite example is Marian Keyes, a multi-million selling writer, happily married, having the life of her dreams... and depressed. There isn't always a reason I'm afraid.

Speaking as someone who is OCD. I'm calling OCD. Not a Dx, just opinion.

If you've not posted a version of this in OCD, I invite you to give it a whirl. You might find someone with a similar compulsion.
