In an exchange with a stranger on Twitter, serial entrepreneur and Tesla CEO Elon Musk was speaking out about his sometimes rocky emotional life on Sunday — yet again illustrating how weird it is when celebrities share intimate details of their lives on Twitter during apparently vulnerable moments.

A fan named Eric Diepeveen was simply remarking on how fabulous and enviable Musk's life appears on Instagram, and Musk decided to respond candidly saying, "The reality is great highs, terrible lows and unrelenting stress. Don't think people want to hear about the last two."

Then another person replied to the comment about highs and lows, asking if Musk might be bipolar. He replies "yeah," but then makes a caveat, admitting he's never been diagnosed as such.

And then he basically admits that his life is hell.

When asked how he deals with all these highs and lows, he says he basically just "take[s] the pain."

CNet points out, "It's important to note that bipolar disorder is more than just severe mood swings, and should be properly diagnosed by a psychiatrist."

So, in summation, being Elon Musk may not be all it's cracked up to be, but having all that money is probably pretty nice.

For instance, here he was clowning around outside the Sydney Opera House with celebrity girlfriend Amber Heard and his five sons back in May.

And in related news, how did Tesla get to shut down the entire Bay Bridge to shoot this clip of the models S, X, and 3 driving alone on the western span last week?
