Thought i'd say another big welcome, I hope you find this site informative and supportive. Like the others say, it sounds like you have a cold and not a sv, so please try not to worry. If you worry like this alot, try keeping a log of your symptoms/feelings - it will serve as a useful record to refer back to should the same thing happen again. Next time you get a cold, you can look back at the log, realise that the last time it happened, your throat hurt, you worried you might v*, felt anxious etc., but nothing bad happened. This should help to reassure you that you're not going to v* this time either.

Not sure if that made sense...hope you get the idea!!
