Hi,
I can completely understand how you are feeling. I live alone, and only moved to the area in the summer, so have no friends round here and feel pretty isolated. I am signed off work at the moment due to stress as well, so don't even have contact with those people. At the moment, I get quite anxious about going out and seeing people I might then have to talk to, so often isolate myself even more.
One thing I have found that helps is every night I write down things I need to do the next day, and one of those things must involve going out the house. Sometimes it is going to the library, sometimes to the supermarket, today I'm going to the post office. In really bad times, it might be walking to the pillar box, or to the end of the road and back. I find having it on a list with other things to do means that I'm more likely to actually do it, and there's the satisfaction of ticking something off the list after. Although going out and doing these things seems stressful and hard, once I've done it I have something to feel proud of myself for achieving, and the fresh air/outside world can sometimes lift my mood too. :smile:
