Like a general depressing feeling that is somehow soothing?
I think I know what you're on about, but I can't explain it well myself. It happened to me a few years ago, and all I saw was negative things, and felt as though that was the way things would stay.
You just have to wait it out until something good happens, and that will really kickstart your mood, and you'll feel better. If my experience of it is anything to go by.
Councilling is a good place to start; it might put things into perspective for you. But like AsiaBunny said, it won't solve everything. That will be down to you.
I reckon you can get through this. I haven't been here as long as everyone else, and I haven't really talked to you much, but I get the vibe that you're someone with a good head on their shoulders.
As far as things around you changing, I can sympathise. I've just finished school, and I'm beggining to realise that I can't muck about with my life anymore, even though I really want to. I still kinda do; I spend a lot of my time playing some kind of video game. That, and the sense of regret that I never experienced a relationship with someone else during my teenage years.
But I always say to myself that if I keep regretting past decisions, I won't be able to function in the present. That's got me exercising, and it's a start, at least.
I lack much artistic talent, but I do have a large imagination if I feel like letting it run wild. Though, most of my thoughts have never found it's way to paper. Maybe I should; it could be a good form of release.
I play bass, but I'm not immensely good at it. I haven't made anything original, and I have a tendancy to choose songs I really like, but end up being way out of my league. Though, Schism by Tool looks promising; I managed to get the main riff down. I'm just not looking forward to the end part. >.<
As for my fursona, he's simply a furrified version of who I percieve my ideal future self to be, which is a heck of a lot more confident than I am right now. I chose him to be a rat because that was my nickname, given to me by my step grandad when I was born. "Tricky Ricky Rat". Silly, but it stuck.
I think I might change his name to Darrell, though; I didn't give the name as much thought as I should have.
