"and the little mirror under the othe other mirror is completly broke! are these expensive to fix? has anyone had this happen before?"
Not as such, no, not in some thirty years, but if there is a mirror 'broke' you have managed to exceed the deceleration-tolerance of your camera body and it will need fixing or replacing.
Seven years' bad luck are extra out-of warranty service, but it would appear you have broken something.
In the photography business, in general, if we can look at an optical element or mirror and describe it as 'broke,' this probably means someone broke it. Probably in some kind of 'breaking things' motion (see 'deceleration)
.
Basically, if you look inside your camera and see broken glass of any sort,this refers to a condition that in the business we like to call 'You broke your camera.' This is usually considered, in technical terms, 'bad.' Do not do this.
