I have not been diagnosed, but my sister in law was a long time ago. And its a household joke that she's nutty. For the BPD and many other reasons. 
But my husband and I have been researching a lot of my mental symptoms and its the only thing I match up with perfectly. So now km looking for a doctor so I can figure out is this is actually whats going on. 
The called her crazy and now I feel crazy too. I'm toxic in my marriage. My moods change by the hour. Sometimes I see it coming and sometimes I have no idea I've been flipping from happy to enraged all day. I thought I handled my mood swings well, but I also thought they were normal because "im a girl and that's females for ya". I'm scaring and hurting my loved ones. I feel like I'm actually crazy and I shouldn't be near anyone I truly love because I'm going to drive them away. But I can't stand the thought of losing them.
