How do I get out of this rut?

I really need some advice. For quite some time now I've been stuck in a rut regarding the weekends. I don't work weekends just Monday through Friday.

Typically on Saturday and Sunday this is my routine. I go to the gym first thing in the morning and do an intense cardio workout. After that I go home and sit in the television for hours and hours on end basically till I go to bed.

I feel completely trapped in my home. I have nowhere to go and nothing to do. I have no friends. Literally no friends. So there's no one for me to call no one to hang out with. And I live in an area with not much to go and do.

This is really taking a toll on my mental health. How can I break this cycle? I don't know how to get out of this and live a little more. I can't stand being trapped in these 4 walls all weekend every weekend.

What can I do?

I forgot to mention... I think part of the problem is that my early morning cardio workouts are so intense they leave me physically drained the rest of the day
