Welcome to the Board, Ignored One.
Never felt my input was much regarded. I guess I never did 'enough'
Are you speaking of input at the Kingdom Hall and service or here on the Board (I hope not)? Read Crisis of Conscience. Let your conscience (and your prayers) be your guide as to what to do.
Usually, there isn't any "leaving for a little while" without someone calling on you but you can try the "fade away". Usually those who move do employ the "fade away" (just forgetting to check in accidently on purpose at the new Kingdom Hall sort of speak). If it culminates eventually in voluntary disassociation or judicial disfellowshipping, your Mum does not have to participate in the shunning. She will not be permitted to speak about spiritual matters with you that's all. True for immediately family only. Others will shun. If you're Mum is all you have or care about being separated from, this should not be a problem but that depends on your relationship. Can sometimes cause rifts as others on the Board can attest to.
Would you like to share a little info about yourself if you can. If not, that's okay.
Just my thoughts....Hope it helps.
