I have always lived by that too. I have never refused a calling. I have definitely felt uncomfortable in callings but have learned and grown as a result of those callings. I felt reservations for my calling in the Sunbeams but I still accepted it and gave my best effort. I have found my faith dwindling and I never want to go to church anymore. I dread every sunday and I find it too hard to take care of 3 extremely active and stubborn children all day everyday and then go to church to have to take care of my kids in sacrament and 2-8 sunbeams (some of which have some major issues, mentally). I feel like an overworked babysitter at this point and I really prayed about being released. I feel so strongly that I need to be in RS. I still believe in not turning down a calling (but maybe we really should be praying about it if we have reservations). Nobody understands what you are going through in your life except yourself. I am VERY good at seeming happy and I almost always have a smile on my face. I hate confrontation, I am a peacemaker and I love to serve others but sometimes, my well-being has to come before others.
