people like that are never good to be around because they sap the energy right out of you.

while that may not be a practical solution right now it sounds like the best thing could be to stand up for yourself. sorry i can't be more specific because each situation is different.

you can do it, you are strong enough.

Well then you damn well better start having an awesome day. Or just power through and have a doubly awesome day the next day to make up for it. There can be no slacking in awesomeness here.
