Hi BPDsibling34
Dealing with a BPD sister can be very though indeed. I have an older BPD sister too and know how challenging and frustrating this can be. I am very sorry that you are having these struggles and are finding it so hard dealing with your sister. It isn't easy at all dealing with a disordered family-member who's also suicidal.
You are seeing a psychologist every week but unfortunately don't find her much help at all. If your school has a school counselor or school social worker, perhaps you could also talk to that person about what you are dealing with.
Having a support network as you go through all of this can be very helpful. It is great to see you reaching out for support and advice here.
You are 14 years old. Unfortunately, our site requires the members to be at least 18 years old. There are other sites specifically for teens that can help you. I encourage you to check out
www.teenhelp.org, a website dedicated to helping teens who find themselves struggling. I've also selected this other resource that could be helpful for you:
Your Life Your Voicewww.yourlifeyourvoice.org/AskIt/Pages/default.aspx1-800-448-3000
Please know we will be here for you when you are 18 and look forward to hearing from you then.
Take care
Kwamina
