Welcome Heather! First, I must apologize for the delay in approving your post. I just finished up my finals for my associate's and have been busier than expected.
I know you say you're only 17, but I'll say I wish I was 17 when I found out about BPD. I know I've had it forever. The sooner you realize that you need to make a change in your life, the longer you can a happy, healthy life.
Please post and no worries re: rants. We all rant around here sometimes.
