hi p.a.,

glad u've found this site so at least u know u're not alone..
i'm not a student but have lived in shared accommodation before, like once with about 8 other people in a staff bungalow (1 toilet) when working in a hotel..i found that when i was in this situation i quickly sussed out when there were quiet times, like when most people where either on their shifts or asleep, to use the bathroom then.

also the good thing was that people kept the doors to their rooms closed, i think if any doors would have been open i couldn't have gone cause as a 'rule of thumb' i'm alright if there's 2 doors between me and anybody else.

so anyway, i think u'll be alright, as once u're in the situation your body will naturally guide u towards the best times to go and how to be as comfortable as possible, so just trust that your body will look after u :-)

also keep in mind that u will always be free to leave, but it hardly ever comes to that as usually knowing u have that final power means u won't need to exercise it, if that makes any sense :-)

take care,
Emily
