Hello hello!
Its saturday already so i wouldnt bank on signing up for volunteer work this weekend, maybe next!
How about reading a book, listening to music, beating your evil room mate with a 6ft stick...wait...hang on...not the last one;-)
Is there anywhere you can go and walk around where you live? Or in easy driving distance...it works for me of you go and walk somewhere just looking at stuff you always feel better afterwards. It is getting into practice of not being so self absorbed, just look at stuff...does that make sense?
Sounds like you would be better to get out the dorm, defo, for a bit:-)
take care and well done on 8 days:-)
