Welcome Kms8qc!
Sounds like you will have your hands full soon with your mom visiting. It is so tough and can be very difficult when you are not only anticipating the visit of someone who may have BPD, but also knowing that your stress levels will be high with worrying about upcoming potential for conflict. How long will she be staying? Do you have any possible plans for brief escapes to get some time to care for yourself? Or perhaps someone to share the load with?
I look forward to hearing more from you and learning about what brought you here. An extra hug to help you get through this time!
Stay in touch. There are a lot of great members here who are very helpful and supportive.
