I guess my T would let me know that it was okay to feel this if this is what I felt. But somehow she would get me to know that she and others care about me and how doing something to hurt me would not be what I really wanted, I just want someone to care, to reach out and help me, to listen. If I was seriously suicidal, than I am sure she would encourage the hospital. I am not sure how friends would respond. I guess I would want the same from a friend, to listen , not judge the feelings, and show that they cared. Kinda like what Tree said her T would do, show empathy and allow the person to talk about what they felt.
Feelings do get this bad, and if someone is reaching out to you, than that is a HUGE step forward in wanting help.
