I'd always go for an instrument rather than a girlfriend, but everyone's different and what helps me may not help you. Playing either calms me down or gives an outlet for my anger, so naturally it helps me heal. I would also suggest guitar since they have a huge variation in price range and you can even find them in second hand stores. Strings should be changed every few months, though you can keep them even for a year or two as long as the sound doesn't bother you and you're not performing which is about £7-£15 a year. You'll get used to it easier if you get a classical guitar rather than acoustic one because nylon strings are lighter on your fingers, plus the neck is wider which gives you more space while learning. Also to add on to what @Carsandsarcasm said, instrument does help you score and/or it's a good bonus ;) especially if it's a portable one (I love piano too, but you can't carry it wherever you go). Edit: congrats Cars on your first performance, I'm glad it went well :D (well, apart from the wait, that's always the ballache part)
