Same, although I don't consider anything I do at work as actually "doing" anything- it's just busy work to get more paper money to do things that appease others.

I just don't care anymore really.
People have told me time and time again about my potential and how bright they think I am, I just don't see anything as being "worth it" anymore.
I don't fully trust anyone anymore.
I try to speak to others as little as possible, I live a fairly isolated life outside of work.

It would be nice to find some kind of motivation, it would be nice to engage in activity- something I could feel genuinely challenged by and take seriously. I used to be interested in a few things, now I don't care about much at all.

I used to really enjoy writing, ever since I was very young.
I like to play guitar sometimes.
Psychology interests me and I considered taking up an independent study of it rather than attend a university, because I think school brainwashes people, makes them callous and weakens their critical thinking skills.

Nothing interests me enough to fully engage anymore, nothing is really challenging to me at all anymore.

I would just push through and start doing something, I like to have a "plan" in place first- that and I'm not very interested in anything anymore.

I hope you find motivation soon. I just wanted to rant because I feel the same way. I didn't add anything constructive, I just felt like venting and i "hoped" you find motivation soon as a gesture(mostly empty) to detract from my self-indulgent behavior here.
