The Borderline Personality Disorder diagnosis must have been tough for you to hear. It also challenged your son. After such powerful information — your son is likely to need some time to adjust.
The person that diagnosed you is very likely to have access to resources in the community to help. I strongly recommend taking advantage of those resources, such as support groups and intensive outpatient therapy programs, as well as any individual therapy at this time. This is an adjustment. The important thing is for you to feel support from people other than your son and work on plans for the future. I wouldn’t try to push a dialogue with your son right now.
In the meantime our our forums are available for you to connect with others for support.
