and yet you came on here... that's a good thing.

Yes talking can help, but the most important part now is to keep you safe in the up coming minutes/hours/days. do what you can, don't isolate... oh wait you already know what to do to stay safe (I hope)
Don't look at as a failure, look at it as a way to slip up, and you can keep going.
Hope this helps... it's hard yes, but it's possible.
