OK, skimmed Discussion--this part is particularly relevant (I'm not actively suicidal, but have had ideations in the somewhat recent past):
"To build a strong therapeutic relationship with a suicidal patient, professionals should aim to use a strong empathic approach to counter the possible feelings of shame and blame felt by the patient (Jobes and Ballard, 2011), provide time for the patient to tell their narrative (Jobes and Ballard, 2011) and be warm and show unconditional positive regard to the patient (Rogers, 1961; Jobes and Ballard, 2011). A person's thoughts of wanting to end their own life and the therapist's attempts to prevent this can create a relationship dynamic that may include control, power, vulnerability, feelings of betrayal and feelings of personal responsibility (Jobes and Ballard, 2011). Therefore, to avoid this power struggle the need for a collaborative and empathic therapeutic alliance is arguably even more essential with suicidal individuals than other individuals."
