when do you pull the rip cord?

I have nothing "post-worthy" per say because all life has consisted of lately is working an extra 4-6 hours a day after I've worked 8 hours and still being ridiculously behind. My human resources person called yesterday, which was the worst possible day for us to talk voice to voice, because when I'm upset or stressed, my voice cannot hide it in the least. Yesterday I did not like my job, I did not like what I went to grad school for, I did not like myself, I did not like being in Houston. Dang you, voice. After she got off the phone with me, she called my district person because she was afraid I was going to walk out and quit my job mid-year, like walk out and leave today. Not good, because my district person came and spent the day with me today after receiving that freaked out phone call. Gahhhh.
Anyhoo, I'm not quiting no matter how miserable and stressed out this mess is causing me to be.
Basically what I got from spending all day with a person I don't know is that:

1) I'm a freaking super star (just kidding...)
She did say that I am way, way too hard on myself because I expect perfection and that's just not possible right now, and that she has to remind herself this is my first year, because she forgets. I take that as the best compliment someone could give me right now.

2) This is one of my first rodeos, but after this year, people are going to think I'm a champ.
Yeah... that's right, a champ :)  I've been told a few times to hang in there and when I make it out of this, I'll be able to handle anything.

I will not quit, I will not give up, I will rock this.

For those out there who are reading and don't know me so well, I don't compliment myself and I beat myself to hell and back somedays, so getting to a point of being able to say these things, joking or not, is progress.
