I lost my temper big time. [Vent]

I have two girls in 3rd and 6th grade. (Today's their last day this school year, thank all that is holy.) They have been A and B students, with an occasional C. This year, I've been trying extra hard to put the responsibility for their schoolwork on them (partially because of a mediation agreement that gives them a little more time at their dad's.)I help them remember, I help make sure they have time to complete their work. But ultimately, the responsibility to do well is theirs, I tell them. I've done that throughout their school life, but this year has been extra challenging.This year has been a nightmare, let's be honest. I'm so exhausted with trying to stay on top of the work they should have done, even while at their dad's. (He's supposed to help them, but doesn't.) So far, we've been keeping up pretty well, with only a few more C's than usual, but this semester one has a D and one has an F.They told me they would stay after to get their grades up. I waited an hour in front of the school, no returns on my texts, no answering calls. I walked all around the school trying to find them. Turns out they were at their daycare.When I picked them up, I did okay for a little while, then absolutely broke down. Said a bunch of things I shouldn't have. I am so angry with myself, and so ashamed. I hardly ever lose it.Now I'm wondering if maybe I shouldn't just give custody to their dad like he says he wants and see how he deals. I'm clearly not up to the job of parenting. I'm exhausted. I'm discouraged. I'm frustrated, and I just want to quit. I can't do this. If it was just single parenting, it would be bearable. A few bad grades wouldn't matter so much in the grander scheme of things. But he's always watching, waiting for me to screw up. I can't handle it. via /r/Parenting https://ift.tt/2LcEwMf
