Feeling helpless right now!

Feeling helpless right now! This is a rant! My mom is admitted to hospital for an operation and I have to do a lot of talking. Talked a lot today initially during paperworks and other stuffs. Though I am not alone but as a 23yr adult male I feel I'm not enough. To some extent I did my best and everything went well. Some situations went smooth some harsh. At the end work is done but instances like calling and explaining nurses about the problem or going to pharmacy didn't go well. I am trying my best to give 100% no matter how much I stuttering but felt guilty about not speaking flawlessly, made a fool of myself( I think).
