Don't pent up negative energy from lab..

And blow it up on loved ones at home (who are clueless and innocent).

Show of hand, how many are guilty?

I am.

Just because they love you don't give you the right to misuse their love to vent out your frustrations and all other negative energy onto them...

You should (or I should) be giving it directly to the person who are making you feel down in the office (or lab)... except to your boss of course (unless you have found a new job)...

Give it straight to the person making you feeling down by telling him/her off. Give a piece of your mind rather than swallow it hard and blow up later. Don't be the implosive type.

You can be nice but firm in your stand and protect yourself from being led downward. Say "no" more often and mean it when you say "yes".

Good luck..
