Can't see my servers in Discord

I'm not sure if Discord related topics go here
I made a new server using on boarding but I clicked the thing that sorts me into roles and now I can't see the entirety of the server or the channels I made. I tried giving myself the specific roles manually but it didn't work. Is there a way to deselect it?
For example there should be a Project B category and a TGA category and way more visible channels under the information tab, now I'm a little worried new members can't even see them and I need to change the permissions
