depression or burnt out or what is going on with me?

I used to be happy then recently i lost all emotions and nothing matters to me anymore. i own a business and it's not slow , it's decent and money doesnt stop coming. i do have a hobby of retro gaming and when i see it on ebay i would buy it or bid on it but once i get it i just put it up on the shelf and just leave it there. i bought a couple of games when it first came out and its been a month and it just sit there still in wrap. devil may cry and dead space 3 i wasted almost a $1,000 this month on buying hobby stuff that i love so much and even spent a good amount of money to build a new pc gaming rig and i just have no effort to play it. what is going on ? i'm pretty much like a zombie that i get up to get to work and once i return home i just sit on my couch and stare at my tv without turning it on. i used to love to drink alcohol and now i don't even wanna come close to it. i stop drinking soda and somehow became addicted to water. i drank so much recently that i've gone through 2 24 cases in 1 week and a half and i barely touch water before. i did a lot of test online on bipolar and anxiety abd depression and it came out minor risk which i think aren't accurate, i tried hypnotist therapy on depression and it didn't help and i also can not sleep at night , i am not thinking about any problems because life are going good. last night i tried to go to sleep early at 10pm and i woke up at 2 then couldnt sleep until 8 in the morning but i kept waking up every 10 - 15 min and had weird dreams everytime i slept what are these weird symptom and how can i fix it on my own. i do go out every weekend and try to introduce new things to myself but after im done shopping or half way through a movie i will always feel like this again ,please help , also i dont have a gf we broke up after she went back to her country couple years ago and its not a reason im sure since this weird things just started recently , thanks
