Well as depression affects us in so many ways, and you say nothing will stopped you being bored, it could well be that you have depression. Depression stops us enjoying things in life, it takes away so much.
If everything sounds boring, do you yourself think it is due to depression. As you know what depression feels like, only you can really understand what is going on.
My question is why are you bored?
Since nothing sounds fun/interesting, you may be bordering on depressed with your chronic boredom. Boredom and depression are two very different things. Boredom typically goes away as you learn to preoccupy your time, however. Depression doesn't.
