英語寫作時一些好的巨型

❶ 請英語好的朋友幫助糾正一下我的寫作：「同時fail掉這門課的影響對我是巨大的，作為在30。。。」

At the mean time, the effect of failing this class can be vital to me. As a student losing both parents in my thirties, I have lost all my incomes. I will need to pay a lot to take this failed class again, and I will have to take an extra semester. When I think about these, I can only feel deep despair and self-accusation.
