• You feel very worried about people abandoning you, and would do anything to stop that happening.
• You have very intense emotions that last from a few hours to a few days and can change quickly (for example, from feeling very happy and confident to suddenly feeling low and sad).

Even though I don’t see him going from sad to happy often, I can observe how a single word can change his mood enormously.

• You don’t have a strong sense of who you are, and it can change significantly depending on who you’re with.

He has complained about this in the past. He doesn’t know what he wants, then he questions that so much that he decides he just doesn’t want to be exist. I mean, I don’t know what I want as well. But dwelling on that indecisiveness can make you suffer. Maybe he is suffering because he questions that so much. I am not sure.

• You find it very hard to make and keep stable relationships.

This is questionable though. It is not stable at all but it is long-term. His former relationships are mostly long-term as well. 3 relationships, 2 of them lasting between 1.5-5 years.

• You feel empty a lot of the time.
• You act impulsively and do things that could harm you (such as binge eating, using drugs or driving dangerously).

Very much, indeed.

• You often self-harm or have suicidal feelings.

Very much, indeed.

• You have very intense feelings of anger, which are really difficult to control.
• When very stressed, you may also experience paranoia or dissociation.

However, these got stronger or happened after a doctor prescribed him tranquilizers and SSRI. I feel resentment towards that doctor because she decided she cannot work with him after giving all those medications for 2-3 months. She just told them that and let him alone with those meds.
