With all this work and effort, I should be paid to do this for other people

 Job searching really is a full-time job. A soul-crushing, paradoxical full time job. 

I've been working on this cover letter for an Undergraduate Advisor position at the local university, and it's like cover letters are these conflicting creations where I have to not re-iterate my resume but at the same time I kinda do anyway? And I've also not had any kind of experience where I've been in an office or advise people, and yet I do recently become such a good office monkey for people, and some without even being in an office. 

The biggest pet peeve I have right now is people giving me advise they have no experience in doing. Such as writing advice. And it's all just regurgitated information from whichever googled article that's been come across, and that is really not the help I need when I could research all of that by myself. Real help comes from someone who has read millions of cover letters and knowing what they need from it, and it just feels super obnoxious to get some kind of "help" via things like "say that you're 'detail-oriendted' and a 'team player."" 

I think what makes this thing more unbearable is that I don't have any close peers here to vent about these things comfortably, so that I would come across as "intense bitter shrew" as opposed to "battle weary compadre who has been my fellow emotional crutch to vent towards."
