Gabbi,
I feel for you and know exactly what you are going through. I too have agoraphobia and know how debilitating it can be. Is you Mum able to come and stay with you? If not, school will be out for the summer in Australia in approximatley 8 weeks, and maybe then you can go stay with you Mum for the summer. Have you been able to go to therapy on a regular basis. I am still going to therapy twice a week. I don't take any drugs to go there, but I am now venturing outside and I take Seroquel, which I also use at nightime to sleep. I have found it really helps me go outside. I counteract the sleepiness with caffeine.
If I can be of any further assistance, please let me know. I also hope that when I come back home next June we could get together.
Sharon
