3) The person frantically tries to avoid what she considers abandonment. The person may act overly needy when their support system is removed, even temporarily, such as when a close friend goes on vacation.
4) The person tries to kill him — or herself or engages in self-mutilation. If you witness this behavior in anyone, immediately call 911.
5) The person is intensely reactive to situations or events that most people would just ignore or brush off. My patient’s reaction to the positive news about her cancer is a good example. Another example is the way a person with BPD might obsess about a situation or statement. If someone tells this individual something in an angry way, then he or she might keep thinking about the statement obsessively and cannot “let it go.”
6) He or she constantly feels empty or not really there. My patient reported these feelings of emptiness many times and often thought she wasn’t really in this world.
7) Anger is their most common emotion even when other feelings might be more appropriate. For example, when a person with BPD learns he/she has won a game in tennis, he or she might rant about the opponent instead of just enjoying the victory.
8) Paranoid thoughts are common. People with this disorder often become paranoid and imagine that people are “colluding” against them.
