abg1202, know that you are not alone. I'm raising two young kids on my own and have a pretty hefty case of CPTSD. Just by what you posted, I can tell that you put your kids needs above your own, and that is respectable, because you are doing the right thing despite unfortunate life circumstances. I constantly worry that my behavior is messing up my kids. They are amazing though...on some of my worst days, when I am cussing, throwing things around, barely functional and can't even get out of the car to walk them to their extracurricular activities, they seem to understand that I'm just not capable of taking care of the things that I normally would, and they are able to take up the slack. Today, in fact, was a terrible morning that was riding the tails of a terrible yesterday, and as I brought them to school, I climbed out of my own head issues long enough to give them big long hugs. Sometimes, that's all they need in order to know that all of my crap is not directed at them, and they can go about their day as normal. In that sense, I kind of have to hope for the best, because that's all there is...the hope that they'll turn out alright and know that my problems are not their own and that they are loved. Right along with that, I also now know that I have to stop beating myself up about the things I've messed up because of the CPTSD screwing with my thought processes. I had to get to a place where I could perform a task and leave it at the point of being, "good enough," or know that a missed appointment could be rescheduled and that it was truly not the end of the world. Not everything has to be perfect all the time, and to strive for that unattainable goal is an exercise in futility. I'm actually still working on that one.
I can imagine that losing a parent to suicide would be absolutely devastating to a child. That's what keeps me here too...my kids, nothing more. I have a strong tendency to idealize death and to hold it up on a pedestal, as if it truly is the ultimate peace. Now that I've lost my religion, it sort of seems that way. Nonetheless, my purpose here on earth is to raise those kids. I know that without me, their lives will go terribly awry. In that vein, as far as motivation goes, like yourself, I struggle greatly. As is often the case, I have to find one little thing to hold onto in order to keep pressing forward. I escape through movies, so for me, it's a scene from the movie, Gattaca. The main character, Vincent, who is of compromised health, swims across a vast expanse with his brother Anton, who is of perfect genetic construction. The main character surpasses his healthier counterpart, and when asked how he was able to do it, he responded:
"You wanna know how I did it? This is how I did it Anton: I never saved anything for the swim back."
It sounds sort of silly, but that one line has carried me through so much. Also, sometimes treading water is enough, and it's what you are meant to be doing for the time being. Mindfulness...staying present and available in the moment and focused on the task at hand...allowing your five senses and the information they are picking up to ground you into the "now" can help to ease the tension of an over-stimulated mind. Your drive and ability to get where you want to go in life will lead you in the right direction. Just realize that, despite your current frustration, the journey is big part of the destination.
