Oh my gosh i can so relate to the thinking about it for ages and then spending anyway - im terrible with money, i have actually gone 2 weeks without food just cos i really wanted these shoes that weren't even in my size they just looked pretty (awful awful awful i know) Now i take most of my money out and give it to a friend of mine whom i trust. Is there anybody you could do this with? I totally know where your coming from though. The impulsiveness is definately one of the worse symptoms of BPD in my view
