This has been going on for around two or three years now.
I have come to the point where I barely leave the house. I has become normal for me to not go anywhere. I don't even go in the garden. I never tell anyone, and have even pretended that I do things, really I get dh to do nearly everything. I maybe go out once a week, but will avoid that if I can.
The mothers at my ds's school have even asked my dh if he is a single parent! I only go out if it is something I can not escape, such as to sort out my ds's i.e.p or statements of sen.
I hate even answering the door.
I know this is not normal, and I want ot take my children out more, it is becoming a problem. I just don't know how to find help, or how to approach my gp.
