I have. I have had helplines accuse me of lyying about being suicidal, goading to me "admit it" (that im lying). Telling me they think I am lying about my feet issues (ingrown toenail that left go for years), and not believing me about my trauma. Alls sorts like that. It contributed to not feeling safe talking to anyone, even my therapist at times. So I get the distress it can cause. The can be horrific at times. I am sorry you had to go through that. I do know a really kind understanding helpline online for sexual assault, I would be happy to pass on.
