IT’S official: money can’t buy you happiness.

Just ask Minecraft founder and recent billionaire Markus Persson.

The Swedish creator of the hugely popular video game, which he sold to Microsoft for $A2.7 billion last year, has revealed his inner sadness in a series of melancholic tweets on Saturday.

It seems despite buying a Beverly Hills mansion for a whopping $A98 million, which he equipped with an enormous candy wall and used to host wild parties, Persson — also known as Notch — is actually super bored and really lonely.

His sad Twitter spree began with this reflective update: “The problem with getting everything is you run out of reasons to keep trying, and human interaction becomes impossible due to imbalance”.

He then said he was hanging out with friends in Ibiza and partying with famous people but “I’ve never felt more isolated”.

He continued: “In sweden (sic), I will sit around and wait for my friends with jobs and families to have time to do shit, watching my reflection in the monitor.”

When we sold the company, the biggest effort went into making sure the employees got taken care of, and they all hate me now. — Markus Persson (@notch) August 29, 2015

Found a great girl, but she's afraid of me and my life style and went with a normal person instead. — Markus Persson (@notch) August 29, 2015

I would Musk and try to save the world, but that just exposes me to the same type of assholes that made me sell minecraft again. — Markus Persson (@notch) August 29, 2015

He also revealed his former Minecraft co-workers “all hate me now”.

To make matters worse, even his love life is in tatters. Persson said he met a “great girl” but “she's afraid of me and my lifestyle and went with a normal person instead”.

But after expressing his sadness for an hour or so, which attracted plenty of love and kind words from many of his 2.5 million Twitter followers, Persson began to feel hopeful again.

People who made sudden success are telling me this is normal and will pass. That's good to know! I guess I'll take a shower then! — Markus Persson (@notch) August 29, 2015

I really appreciate all the offers to hang and talk and all. As an introvert, new friends is hard to do even when fine, but it means a lot! — Markus Persson (@notch) August 29, 2015

And just venting and not feeling like I had to hide made it feel a bit easier to cope with already. ❤ — Markus Persson (@notch) August 29, 2015

That is, until an unfortunate encounter with a jellyfish overnight ushered in some new problems.

A jellyfish stung my knee. Surprisingly didn't hurt that much, and at least two people offered what I would consider a bad solution. — Markus Persson (@notch) August 29, 2015

Yep, knee pee. — Markus Persson (@notch) August 29, 2015

Hang in there, buddy.
