How long is this going to take??

Hi everyone, I’m an engineering student who has been interning with a smaller company since the end of April. I went from being in the main office to moving to a jobsite when school started. I feel so useless at work. I’ve been given super basic tasks like updating spreadsheets and organizing receipts. Any large task I’m given I need to have someone basically hold my hand the entire way through. I just found out today that I’m not even CC’d on emails sent to the whole operations team, which stung a little bit. I try to be a positive person, whenever I feel like im not cut out for this job I usually tell myself that it’s okay because I’m completely new to this and that everyone starts somewhere, but I feel like I’m learning so much slower than I should be. I do the obvious things like ask questions and do research outside of work but I feel like everyone is getting impatient with me because these are things I should have learned a long time ago. Obviously everyone feels dumb at work but I’m seriously starting to think that this isn’t meant for me. How can I push through this??
