You do sound depressed. I have experienced pieces of what you experience. Mostly, the boredom. You may be bored because you are depressed, you may simply find what is around you and what is available to you to be uninspiring. I suggest you find some books. There are more bad books than good ones, so check it out for like 2,3,4 chapters and if it doesn't feel right, if you don't like the style, go get another one.

I think books are much more stimulating than other media. They give you much more information and more time to contemplate it. Keep searching and try to find more and more and more things on this earth. Pop culture is very narrow. It deals with film, music, fashion, sports, and politics. It rarely leaves these boundaries to explore the real world. So explore more things. Explore your neighborhood, go to parks, look at clouds, sit in the grass and read books or strike up conversations with strangers or do anything else you want.

Just realize you've seen the tiniest piece of the world and you have so much out there to discover and find interest in.

Also, you can always see therapists. Find the right one, find someone who listens and cares, and build a relationship. Build your mental health if you think it is faltering. There are plenty of ways to do this without therapists, but they are trained to help you and usually do.
