i just cried over a phone

i believe i am quite a positive person but the fact is i am quite emotional too. Though it's getting better when time goes on, i learn and be mature, still when it's about my family, my responsibility as the elderst, when there is a burden on my shoulder and i find myself can't cope with, i am easily feeling upset. Just a while ago, i came out a budget and after discussion with my husband and aunt, we decided to fund my youngest sis to go study in Taiwan. Though it sounds quite positive her study will be funded fully (at least my parents don't need to worry), i have more to do now. I got to advise my sis is that what she wants? And what kind of future she would like or foreseen? I got to help my parents to get through this financial crisis. I got to consider my husband's feeling if there is by any chance we need to use our own savings to help them. All these become the unsolved problems clearly after i talked over a phone with my aunt. At the end, i just cried. I know it's just too stressful for me right now. I just realized nothing much i can do. And it does matter if i delay to help out, things will just getting worse. Yet, i need to be strong. Thank God that i am a Christian, i believe God can watch over me and guide me. And i certainly believe, it's a life process, at least i learn this when i am young, i can cope if there is bigger problem next time. Does this sounds positive then? God, please grant me the power!
