Hi and welcome,
According to this website, BPD have 10 % chance of suicide.
https://bpdfamily.com/content/borderline-personality-disorder-clinical-overviewAlso there is a section on suicide on this forum if you type it in above in the "Search BPD Family Site".
I am not sure I can answer about the feelings of BPD or what exactly Level 1-2 mean. However, please take a look around here as there is a wealth of information as well as book suggestions to read. It is great you had some therapy.
You are not alone, please write more about yourself as you feel comfortable.
