Let's see what may help you.....
I suffered a complete breakdown following a severe shock a year ago and didn't leave the house for six months. On- line grocery shopping provided a solution for food and household necessities. The longer I stayed home the more daunting going out into the world became.
My first walk out was to therapy and though only a 15 min walk it seemed an eternity.
I began my road to recovery by taking short walks, in the evening, (I felt more invisible in the dark) and I found a talk, or Webinar that kept me riveted for the duration of 30mins minimum to listen to on my earphone.
From there I progressed to short social gatherings, which though triggered anxiety I forced myself to participate in though I was pretty passive. There is a woodland near my house and walking there renews me, by the end of the walk I am usually calmer.
Finding an evening class for something you love to do may be a good first step to breaking the isolation mode because isolating really is addictive and it is difficult to break the cycle.
