I type "resentment breeds" into Google and it automatically fills in the following options:

resentment breeds contempt
dependency breeds resentment

Contempt, resentment, dependency... and I just follow it all with a sigh.

It's really hard not to get overwhelmed, to get trapped in circular thinking that constantly just brings me back to negativity and anger. 

That is, when I can muster enough energy to be angry.

Sadness can get to anyone - it's not like you're not perfectly normal when this stuff makes you want to give up and sink to the bottom. But there's a difference between accepting what's happening as being something temporary or able to be changed, and accepting that it will never change and it's useless to try anything else.

Be angry when things aren't "right" - whatever that may mean. But don't just be angry. Do something about it.

My problem right now is anger mixed with fear. The anger is the stand up and shout feeling, and the fear sticks out an arm, grabs anger's coattails, and pulls it back down into its chair. 

Because what if someone noticed?
What if someone heard?
What would we do if that little bit we have, that's not even enough to get by on right now, was taken away?

Powerless sucks. It feels like dependency and it breeds resentment. I want to depend on myself to stay alive and make it through another day/week/month/year. But when every small move is dependent on someone else - their whim, their mood, their decision to not mention something to you until the last minute or to hold onto a grudge - it's hard not to want to give up and give in.

Screw that.

Google also said "familiarity breeds resentment"  
.....so I'm going to try something new.
