Do you have any money, OP? I can suggest you try and travel. Go somewhere spiritual and out of this world, like India. I've been there many times and it's a life changing experience. You'll never look at humanity or your own existence ever again. Life will have a point.
If not, what I can suggest is you keep active as much as you can. It's strange a doctor would suggest you actually take a "year off". If anything, that would promote procrastination. I'd be worried that sitting around every day taking it easy would become too relaxing and easy that you'd have trouble getting back to real life. But that's me.
If you have a job, that's good. If not I'd suggest that, perhaps. This way you're at least going to be physically active and waste a few hours a day. You can easily go mad if you spend day after day on the internet, and believe me, I know. I did the same thing for 7 years of my life after getting kicked out of high school. I just slacked off, played video games and browsed the internet. Such a waste of time and it nearly ruined my life. I eventually got a job, saved money and backpacked around Asia and South America for a year. Now I have a nice job, shit doesn't make me anxious, and I can live relatively normal.
Don't go down the medication route. Anti-depressants cause more harm than good. If you're feeling down find something to sink time into other than mindless browsing. Read books, find a second hobby, smoke pot. Just do anything to remind yourself depression is a state of mind and isn't real. Eventually you'll get back onto track and live life again.
Like somebody said above, in the end life is eating and shitting, just like any animal on this planet. We all go to school, get degrees, get jobs, retire and die. Life itself is pretty bland. But it's what we do in between these phases of existence that defines what life is. Don't drown in cynicism, because it's easy to do that. We all know the world is filled with appalling evils. You can't change that (though you can dedicate time to making a difference). But you can change what goes on in your daily life. What you do, who you meet, and who you share experiences with. That, in the end, is what life is.
It's like climbing a mountain. There is no real point and you could die from a multitude of reasons, remembered by nobody but a handful of friends and a pile of stones where you dropped. But, if you managed to climb that mountain and make it back down, you'll have stronger friends, more experience, and a lifetime of memories and stories to tell. And, you'll be able to tell people, "Yeah, I did that." Egoistical perhaps, but we all have egos.
