Completely normal, and very common. Walking into a room full of strangers takes courage at the best of times. After a cardiac arrest, when you may already be dealing with anxiety or a changed sense of who you are, it can feel like a significant step.
Most people who have attended their first SCA UK meet up describe the same thing: it was harder to get through the door than they expected, and far better on the other side of it than they had imagined. The moment someone else in the room says something you have never heard anyone say before, and you realise they understand exactly what you mean, is one of the more remarkable experiences recovery has to offer.
You can always come for an hour and see how you feel. No one will put you on the spot or expect anything of you. And if you want to ask questions or read reflections before committing, our blog post Together Through Recovery captures what attending felt like for those who came.
