I'm sorry you're feeling this way, but it's perfectly normal to experience these emotions and anxieties.
Whilst you're waiting for others to come along, I just wanted to mention the Helpline. If you feel it might help to talk, do give them a call. They're great listeners and can direct you to other sources of information and support too.
They're open today 10-2 and Weekdays 9-5 on 0808 800 6000.
