jeez... by now some of you know I'm a grown man, still living w/mom

well... it works out better that way since im her unofficial full time nurse...
yesterday i woke to her usual moaning (every utterance is a prayer ive heard) combined with some general mumbling about dis-satisfactions with me..
now, if she would come straight to me and explain, like an adult, what the issue is, i'd be happy to assist her any way i can... but it's that illegible grumpy moan she uses in the other room, then slamming drawers and such...
i told her, look mom, talk to me... isn't it obvious i care? no use, the match head was ignited and the fire she burned...
i refused/declined to spend any day with this dysfuntional family of mine... hey, i just can't take it... don't care what they think anymore.. gonna do what i do, continue to help mom even though she's appears ungrateful and blackened by all her experiences at times... i know they've been rough on her... but she's snapping at the wrong reasons... i still feel pity... and that, regardless of all logic, created this compassion... i mean, after, she's my mom... what am i supposed to do... walk away? i can't...
but no more b.s. from the sibs... her either... i'm a good guy... if they can't see that, then, oh well... but i'm not attempting in the sibs case anymore.. it's been ferociously futile... i'm no closer to them now than i was 29 years ago... time for me, and them, to grow... if they aren't coming on the ride... soyonara baby... best of luck...
