Hi
Wisdomsearching and welcome to the board. You are in the right place for certain. We can all relate to coping with a family member with BPD or suspected BPD (many of us have family members who have not been diagnosed - uBPD). There are several people who post consistently who are dealing with a sibling with the disorder. We get it.
Behaviors that you have described here are very hurtful and damaging so of course you get upset. Your description of going from guilt to resentment and anger is such a normal response to this type of situation. We can listen to and validate your experience. We can also help you learn to use communication tools and understand your sisters defense mechanisms as that will help to depersonalize her behaviors. I'm not saying you will feel nothing when she does her usual but you can make it so that it does not hurt as much. Communication tools can help you respond in ways that are less likely to set off your emotions and hers.
Would you be interested in reading about the communication strategies we have here? If so I can give you links to read.
We also have the
Survivors Guide located on the right side of the page. Each number on the list is clickable and expands to give you more information. Using the guide can be helpful in determining where you are and where you may want to go next while working on healing. Healing and recovery is not a linear process. Another good place to start reading is our article on
F.O.G. (Fear, Obligation and Guilt)Wisdomsearching, I hope you continue to post here as you feel the need or desire and read some of the articles we have available. Like I said above, we all get it and most of us have been in a similar situation. Things can improve for you and you have found a great place to work on it.
