Comme d'habitude, la belle Claire a raison [DEEP SIGH]. I checked out your CV, and was immediately struck by a) how the formatting was not regularized, and b)how the spelling was so bad that you had even mis-spelled the names of places where you had trained, and characters you had played. As Simon Dunmore says in his excellent book on geting work as an actor, there are an awful lot of directors out there who either have English degrees, or who care deeply about the written word. (Or both, of course.)
If you can't spell, then find someone who can to check your professional submissions for you. As Allan (x2), Forbes and Eliza point out, this is a business; and as all the people you will make submissions to are going to be perpetually swamped on a daily basis by applications, letters of introductions, speculative CVs etc etc, it's worth remembering that they will also be perpetually and actively looking for reasons to whittle said applications down to a reasonable number. A poorly-written application provides them with the ideal excuse to put it in the 'no' pile.
Also, to return to the main substance of your post, I'm afraid I don't think it's for you to pronounce who is a 'shit' actor or otherwise. We've all given both good and bad performances; and I suspect that there are plenty of parts that all those 'shit' actors would be far better suited for than you (and vice versa, of course). One of the things I've learned about this profession is that the majority of actors are generous-spirited and supportive: in fact, I'd go so far to say that being generous-spirited and supportive is in itself part and parcel of having a business-like attitude to the job of acting.
This is all meant supportively, please be assured. But remember that 'talent' and 'castability' are NOT the same thing. Only last week, a good friend of mine (whose daughter is a supremely beautiful, auburn-haired actress) was bemoaning the fact that her offspring was just as talented as Karen Gillan, but far more beautiful, so why hadn't SHE been seen for Amy Pond etc etc. As I had to inform her - very gently - the mere fact that daughter looks like a super-model was grounds enough for disqualifying her from consideration.
The most positive thing you (or any actor, for that matter) can do, is work out as best you can your OWN castability, and chase the roles that suit you, and not the roles you think you should have.
(Having said that, I'm just off to do The Sound of Music for a year, and my contract assures me that "in addition to playing your own role, you wil be required to appear as a nun in certain group scenes." I certainly didn't see THAT one coming...)
Sincere best wishes
