Thanks for the responses, as said in the original post I never go outside alone but this has meant that I rarely go out at all - now is the most often at once a fortnight for therapy (my social worker comes to the house) but never anything else. I mean I literally get into the car with my mum who takes me to my therapy and then at the end of the session brings me back home. I go shopping rarely and with my mum who never leaves my side - usually every few months or so and only at quiet times of day. I go to the countryside about 3 times a year, again with my mum and usually sisters, although sometimes less and that's it. I find putting the rubbish in the bins fairly problematic, in fact even thinking about it, I rarely go up the end of the hallway where the front door is.
I started treatment for agoraphobia three weeks ago, and things have already been improving quickly. So I want you to know that no matter how bad you feel your agoraphobia is, that it is something you can triumph over when the time is right for you.
I think the problem for me is I don't want to go outside, because my abusers live within a mile of my house and there's too much of a chance to bump into them, if/when I move away this is something I am sure I will still have a problem with, but less so and then I will be willing to tackle it. At the moment, it's not so much a problem than an inconvenient need to remain safe.
I like your plan Barbarian and particularly this:
Just because I did good on one day, didn't mean I had to stay at that level
That is possibly the best thing anyone has ever said, because I know that sometimes I don't push myself for fear that then if I've done it once, me or others will expect it of me more frequently.
Being in the truck was my "shelter" and I didn't feel threatened most of the time.
I don't feel scared in our car unless we're parked for a while at certain places, then I lock all the doors and duck down so no one would know I was in the car unless they came looking for me.
I have times when I don't even go into my yard to work on my gardening.
So glad to know I'm not the only one who does this - my garden is enclosed and high walled, so why I feel unsafe out there or that it's too much effort to get out there is crazy, but it does happen a lot, I just feel uncomfortable and at greater risk than normal and scared that the neighbours can see/hear or are judging me.
By reading others' experiences I feel less alone and can understand and interpret my own experiences better. So thank you.
