Hi Spacey and welcome to the BPD family! I am so glad you have found us, but I am very sorry for the difficult situation with your daughter that has brought you here. Having a 21 year old daughter that has been diagnosed with BPD, I certainly understand that feeling of not being able to cope at times. It is a terrible feeling and I am so very sorry that you are experiencing it. You are in the right place to find others who totally "get" where you are coming from and also to learn strategies to better deal with your daughter's worrying behaviours.
A good place to start is by perusing the excellent lessons on the right hand side of this page
When I joined this board a little over a year ago, I, too, was at my wits end and truly thought the situation with my daughter was possibly beyond hope. Presently, things are much better... .dare I say even very good... . and I truly have to credit this wonderful forum and the people who post here, along the myriad of resources available to us members to help us learn new methods of communicating with our pwBPD.
Self-care is essential, Spacey. You mention being worried for your own health due to the burden you carry. Are you doing anything to take care of you? You mention the only other support being your mother... .does she also live with you and your daughter?
Please share more when you are ready, Spacey. I am glad you are here and want you to know that you are not alone. This forum is full of the most caring and compassionate people... .good parents, like yourself, faced with horrible circumstances. We are all here to learn and to help each other... .
