My problem is i can't convince myself to do anything other than stay in bed and rot, besides going out. In terms of activities i'm 95% outside and 5% inside. For example i found that i like studying around others, but when i'm attempting to do just that my brain starts the same routine "This is pointless. You won't go far", etc, etc. Even when i have to do activities with others my brain tries to convince me to go home (or stay home if i'm already there) and stay in bed.
I used to run, and i like running (paradoxically enough) but like everything else i can't convince my self to make it a habit even when i want to.
