you just need a basic plan, rip a sheet of paper out of a notepad and fill in the hours of the day with activities, sort of like your own personal cbt session for the weekend. after breakfast go out and play a sport, basketball, soccer, even if its on your own at a park somewhere, or walk somewhere and get some oxygen therapy. learn an instrument, book it in for 1 hour, go to a cafe/restaurant with a magazine and try out some dishes on the menu. read a book for one hour. see movie, visit a friend. go to the city and check out the shops. travel somewhere. start writing a song or a book. start chipping away at a skill or a hobby.
whatever you do dont waste your weekends. there is little point unless you want to just relax and do nothing.
