My keychains haven't been working so I deleted something and I forgot what it was

Question

My keychains haven't been working so I deleted something and I forgot what it was, but it was obviously something big and now my mac is saying that it cannot find a place to store a keychain or there is no keychain available or something along those lines. I need help with this problem ASAP. This is how this problem started:
1) A couple days ago i changed my password and turned my computer off.
2) Today I powered up my mac and it says "This application would like to use keychains please enter your keychain login."
3) I didn't know what the password was so I went on Safari and the messages kept popping up.
4) I went on Safari typed in my problem and it came up with a question similar to mine on an apple webpage.
5) I clicked the webpage and it was telling me these steps to follow to make the pop up messages stop and how to reset the keychain login password
6) I followed the steps and one of the steps were to delete something so i did
7) I then tried to reset my default keychain but it said "This specified keychain could not be found"
8) so i got worried and restarted my computer and it still had the pop ups and i had to relog into my account.
9) I got relogged into my account and the messages kept popping up.
So now i come to you all smart mac users asking for your help and ASAP. Please help me I don't know what i did and i want my mac back to the way it was.
HELP ME!!!! Answer ASAP PLEASE I NEED YOU SMART PEOPLE!!!!!

Hello Chewey
Best thing to do here would be to reset your keychain to factory default. I’ll explain below. But first let me explain the consequences: doing the action below means that your iMac will forget your passwords until you enter them again once more. Think email passwords, wifi passwords, website passwords etc. You don’t have to change all these passwords, you will have to simply enter them once more, so hopefully you either know them by heart or wrote them down in a safe place at one point.
Either way, I think at this point you have little choice, as your description makes me think your keychain is completely broken anyway unfortunately.
So here we go:
1/ click on the Finder and locate the menu called “go” in the upper left corner of your computer display. For reference, this will be somewhere to the right of the classic -menu. Once found, click on it and select: “Go To Folder”
2/ Type the line below in the box that appears, including the ~ (or copy-paste it from here of course) and click the [GO]-button.
~/library/
3/ Now the Finder will enter a folder with a lot of technical-looking folders. Scroll around until you find the folder called “Keychains” Move this entire folder - with contents and all - to the trash.
4/ Once trashed (you don’t have to empty the trash if you don’t want to) restart your computer via:  > restart. If this doesn’t work (might happen if a lot of password prompts are hanging around for example) just forcefully restart it this once.
Your issue should be solved and you’re now left with the slight chore of re-entering your passwords one-by-one as your computer asks for them.
