Introduction

Hi, I am looking for someplace that I can get the information to help my sister.  I think she may be showing some signs of BPD.  I have talked with her about getting help but she refuses to discuss it.  I hope that I can get some suggestions as to how I can encourage and eventually convince her to seek help.

Welcome Gracie2018: 

I'm sorry that your sister may have BPD.  What signs of BPD is she exhibiting?

You are a good sister for wanting to help her.  She has to decide that she wants help, in order for it to be successful.  What you can do is tailor the way you interact with and react to your sister.  With setting your own boundaries and using some specific communication techniques, you can hope to improve some things.

There are some links to some good information in the upper right side of this post. 

Below are are few links that could be helpful:

Hi Gracie2018

I would like to join Naughty Nibbler in welcoming you here. She has given you some great advice

Dealing with a BPD sibling can be quite challenging. What are the signs you see that lead you to believe she might have BPD?

You have talked to your sister about her getting help but she does not want to discuss it. Do you feel that she at least does acknowledge that some aspects of her behavior are a bit concerning? Do you feel like she in any way has ever acknowledged that there might be something wrong with her behavior?

Whether she decides to get help or not (unfortunately) ultimately isn't something you can control. What you can control is what you do yourself and I too encourage you to focus on the tools and resources on this site. The structured communication techniques described here (such as S.E.T. and D.E.A.R.M.A.N.) can be very helpful. By applying these tools you will change the dynamics of your relationship with your sister, regardless of whether she changes or not.

Take care
