I have a really stressful job which can sometimes lead me to get stressed easily around my girl when I come home from work.

How do I make sure I keep frame even when things at work are hectic and are driving me insane?

I do a pretty good job of keeping it under control at work because I'm the boss and it is very unusual for the other employees to question me or go against my decisions.

However as the boss when things go wrong I feel responsible for the whole team and that I've let them down. This is what creates the stress.

Any ideas?
