<Snipped quote by Techspert>
But this is affecting everything. I literally had to take a couple seconds to remember that it's "affecting" not "effecting" in that previous sentence. My mind isn't just shifting focus, it's losing focus on everything. And I don't have any passion and effort to give. Even my dreams for the future leave me unmotivated. Things I enjoy doing I end up getting bored with immediately. And I'm not talking about things I could do years ago. 6 months ago I could learn a new incredibly complex concept easily, and now I can't understand things half as complex. Even my personal imaginations have lost their appeal and creativity. There's just nothing left from me.
Dude, i deal with that all the time. It's just your brain processing all the stuff to find what it wants.
As for your motivation, you just have to keep at doing something, especially using your imagination if you want to keep it. Otherwise, it just gets dull. Finding new things to do can give you insight on stuff you want to do. Also even if your imagining the same stuff or thinking up new stuff, try to see if you can change something different about, that way you try to think outside of what you already know. Persnally i've only ever had the motivation to stay alive, get through the day, and enjoy time with friends and family. I didn't and still don't care about my grades, let alone money, but at some point i have to get on with life and do stuff, because i realize i'm not gonna get any where with doing something. So with or without motivation, i do what i need to and what i want to.
