Ask HN: Working from home & depression

I have been working from home for 2.5 months with no option to go into an office for social interaction. I noticed in the first month I was starting to get cagey so I joined a gym to go to evening classed and moved my evening piano lessons to lunch time to get outside for a break once a week. I also try walking to the local gas station for any trivial treat or newspaper...But I feel that over the last few weeks my moods have been really affected by working and living in the same 1200 sqft. How else can I change my schedule to avoid the loneliness of working from home and the familarity of living in your work area at night/weekends.
