What more can I do about how I am feeling?

I am 19 and for a long time I have felt like nothing.

I felt that my life was not worth living and that I did not want to do anything.

I know I have great potential and that if I just looked for an opportunity I would be able to get better, but at this moment I have no desire to do anything.

I feel like nothing.

I would have killed myself a long time ago if it wasn't slow or painful.

Instead I settled for becoming addicted to the internet: spending hours playing online games, mindlessly reading random articles, and watching and masturbating to porn. It started becoming really bad in college when I would stay up all night and stop going to classes.

When I did not have access to the internet, I would drown myself in fantasy novels. Reading for hours on end, burning the midnight oil, and neglecting basic bodily needs like going to the restroom or eating and drinking.

Now, I have moved back home with my family and they are helping me get back on track. I have stopped going on the internet to play games, and whatnot.

I have also began meeting friends in my hobby of Parkour again.

However, I wish to know what I can do to further facilitate my desire to live productively.
