I have social phobia (dianosed AvPD) and I am pretty much isolated.
I have had this most of my life (from early childhood, and had my first panic attack at 19 which I eventually understood to be agoraphobia) and used alcohol/Ativan/Valium to cope for most of my life before I got to rehab.
Struggled with AA and found an online alcohol support group which helped before I was diagnosed officially in 2006. I have had therapy, counselling etc etc and various attempts at medicinal remedies (and some quite frightening attempts).
Have just been given something from my new doc which seems to have taken the edge off (and without any reaction - so far).
I am quite satisfied with my diagnosis as it has answered a lot of unanswered questions, as did 10 months in rehab, but still feel there are other elements to my 'condition'.
Still struggle on a daily basis with *empty days* and any additional stress factors that life throws out.... especially now the gov't has moved the goalposts for disabilities and fitness for work. It's my turn, now, to be assessed and moved from Incapacity Benefit to ESA or Job Seekers Allowance. I am pretty stressed about it especially after hearing some horror stories.
I have pretty much got used to isolation as a 'preference' to social interaction (or any person interaction, including, pretty much, my family).
I feel safer online (to some extent) but it is preferable to face to face contact.
