OK, be kind, patient and have sympathy for my inability to understand computer lingo. [View all]

I have a Samsung Galaxy E and am still learning how to use a computer. I would like to put a video onto DU but when I googled help regarding how to do it and I tried and I wasn't able to do so. There were step by step instructions on You Tube but I keep fucking them up. It is a video from The Castaways called "Liar, Liar" (for loser 45 of course). Please don't tell me to get an Apple since I have limited funds and time left on Earth (seriously it isn't worth the investment when it comes down to it...ask my doctors). I get easily frustrated with computers and there is no one I can go to for hands on help since I am stuck at home alone most of the time. Can you stick it on this post and I can somehow stick it on one of my own later? I do not know how to link, copy, cut and paste, etc.

Thanks!
