I'm sorry for what you're going through but glad you have found a community where many of us have been through similar experiences, and we can learn from each other. You will get good ideas and support here if you continue to read and post. Mostly we are all here because someone in our lives has behaviors that are characteristic of BPD. They haven't all been diagnosed with BPD, but it's the behaviors, and how we deal with them, that are important.
Things can change, but we have to be willing to do the work to change them. Well, at least start the process. It only takes one person to change the dynamics of a relationship. Does this guarantee a happy, sustainable, loving relationship? Unfortunately, no. What it does though is give things a better shot at becoming that way.
There are some basic tools and lessons in the sidebar to the right of this page that can help you make changes. They are worth a read and can help to improve all relationships in your world if you take them to heart and put them to good use. If you can tell us how you think that we can best support you, I'm sure that we'll do what we can.
Reading the posts of others can help you see that you're not alone in what you are experiencing. When you feel comfortable, it also helps to respond to them. This helps everyone learn and grow more and faster.
Learn all you can about BPD. In addition to the tools mentioned earlier, there are workshops on the boards that give some good practical pointers on how to deal with communication, rages, etc. The articles are also very informative.
I look forward to reading more of your story and progress.
