Patience....or lack there of

I can be super duper patient with everyone regardless of what they may or may not have done..but when it comes to myself and my mom i have no patience what so ever...i want to push myself and then i hate myself when i fail...i cant do anything and the smallest tasks still tire me out completely...i went to the grocery store ..a  normal trip to the store..i dont think i did anything out of the ordinary..but well i just feel like i should be doing so much more..and im tired..so so so tired...i spent the morning laying down and finally got myself to get up and go to the store..still forgot a couple things..but really not even or than two hours..and im ready to fall over and take a nap..im so worn out...and it frustrates me...so so so much...-sigh-
