On being writer's blocked

I have to admit, I've been blocked. For those of you who do not know, I have a passion for writing. I've been writing stories since I could write, but I do get blocked often. In the article here, Beth Ann talked about there really not being such a thing as blocked. Maybe she is right. The truth is, that for the first time in years, I'm writing in my native language. I'm also working on my first novel. I've written fan fiction before, but this is different. Self-doubt has always been a big problem with me, and that is what I'm doing. I'm constantly questioning the story. Should I put a love triangle in it or not? Should she marry this guy? Is this passage good? It's so hard to resolve these questions. So maybe I'm just scared that it'll be crap, and I'm not good. I have to believe that I am, though. So I need to square my shoulders and soldier on, because I'll regret it if I just give up.
