Gosh I’m so sorry for your experience. Having worked with those type of calls in the past I’d never leave someone who had asked for help like you were, in fact even if you hadn’t asked for help and your colleagues could see it was a difficult call I would’ve expected them to check in & take over if needed. Does your manager know your history and why it triggered you so strongly? You don’t need to tell them everything but they have a duty to protect you and it’s in their interest to do so, so you don’t go off sick, if they aren’t sure how to support you ask for a referral to occupational health. Your reaction is valid, no one knows how they’ll feel during those calls, dv background or not, and we’d always say go for a walk, settle your mindset and return if you feel able to or talk to a manager if not. The old ‘pull yourself together’ advice is rubbish. If it happens again you don’t even need to wait, just calmly say to the caller I am ending your call now and hang up. Remember the caller was in the wrong, not you. Don’t let one bad experience knock you off course, you know abuse is wrong and you don’t deserve it. xx
