I used to feel like that lots of times. I don't feel overwhelmed too much due to SP alone. Only time I would feel like this due to SP alone is at a party or a large gathering with lots of unknown people. I don't get invited those kinda things much anyway.
Having said that, I do feel constantly overwhelmed at work. That is mainly due to amount of work and my work output. I mean one of the root causes of this is SP. You know being reluctant to call or meet with people, cannot concentrate and cannot communicate very well. The other cause is I don't work very well under stress and this spirals out quickly.
Oh yeah.. I time my visits to the water cooler so I don't have to talk to people to much. And yeah when I am overwhelmed .. .. When I was at uni/school, library was always good... especially the self study desks. Hmmm hiding in uni library upstairs between the shelfs of old books ... ah the memories.
