I, also, am running on very little sleep due to thoughts that just wouldn't stop, and you're not alone with the constant cycle of thoughts. One day....or sometimes for a few hours...I'll feel on top of things, motivated, willing to do whatever it takes to better my life, and then I'll not care or feel like I'm stuck and will never get anywhere, and the latter have been pervasive lately though I know it's not accurate. You're not alone...hang in there, that's all we can do at times.
