Another shitty weekend

BLOODY HELL! Another shitty weekend and i feel like crap again emotionally, physically and spiritually drained. I'm so lost, clearly i dont want this bad enough or have the drive to succeed in losing weight this time, i dont know what to do. I "start again" every monday and go really  really good during the week and then BUST friday, Saturday and sunday. Well thats not good enough. Im back to not wanting to run again as its getting harder and harder. Thats my gripe for today. Um just feeling "glass half empty" today, a bit down in the dumps
