I'm trapped

It's not like I came to a sudden realization, I've been thinking about this every single day. I haven't been more than two miles from my house in almost a year. Last January to be exact. The few times I've been that far were mandatory for a drug test so I could get a job working out of my house. There have been weeks where I haven't gone anywhere and at the most all I've done is drive around a few blocks with my sister. This summer I went to a few close by gas stations, but that's it.
I'm currently taking 20mg of Prozac and that's it. I don't have anything for any additional anxiety. I stretched out my prescription as long as I could by not taking it everyday because the doctor that prescribed it is so far away.
I hate the winter and even when things are "normal" I tend to shy away from going anywhere during the ice/snow months. 
I'm having a hard time seeing the end of this. This is the longest period that this has happened.
