I feel you completely. I have two younger brothers, the older of which was pretty sick and difficult as a young child. My mom had to focus all her energy on him and my other brother since they were younger, and was too stressed out to deal with her mentally ill adolescent daughter. The fact that my father was so stressed from work that he didn't want to have anything to do with us kids just made things worse.

I believe that invalidating environments like ours are likely to cause BPD, so I'm sure a lot of us have similar experiences.

Luckily after I moved out and went to college I've been able to get along a lot better with my parents. I also think it helps too that my brothers are older now. Opening up a little bit with my mom about my illness when we're alone together has made things a bit easier too.

I'm sorry you're still going through this. I hope things work out for you .
