hard conversations are really hard (duh) so your body will often like physically try to stop you saying it. you’ll lose the words and not know how to start. My trick (learnt from when my dad told me my mum was gonna die), is to start with a line that you can’t come back from. something like “I’m sorry to tell you this”, or “there is something important I need to tell you”, or “let’s sit down for this conversation”. You can’t come back from that, the conversation has to happen, you have to tell them then and there because you’ve announced that it is coming. Having that first line planned, but not the whole conversation, I find really helpful because it means I know how to start, I know I’ll actually go through with it, but I don’t agonise over the details of the rest. Somehow makes it less anxiety inducing. in the moment of saying it it often makes you feel sick but it forces you to come out and say it. It’s always worked for me!
