Never happened to me yet, but yes, usually there are (in Spain) 1 per day at least. More in CataluΓ±a, but weh.
And well, it's not as stressful as you think, but you have a big responsability.
I prefer with others. Yes, alone is pretty awesome because you have your freedom, but until some point. It is kinda bored in the long-term.
Living with family/friends are the best way, if you understand each other.
