I believe that I have always been borderline but how much it shows or comes out is dependant on what life throws at me. When things are calm, no new relationships, etc, I've gone years with things more or less under control. Bad periods, bad days, definitely but I can cope and most people are none the wiser. When I'd get emotional, I'd isolate myself until it passed. But throw trama, new relationships, stress, family problems, or work issues at me and all the traits I've had in careful check come back with a vengeance. And TA-DA, I'm hear because of it, trying once again to put everything in check and finding it very hard this time.
