I want to tell it all but I can't

I wish I was a writer that can tell it all. Sometime I feel like I know all about a murder but I can’t tell the story. I don’t know any murder and the story I need to tell is about me but I can’t tell it. I want to express my feeling to a point that makes me feel so proud that I can tell it and make me feel better. I really need to start blogging better, expressing more my feeling and thoughts because I cant hold it in my mind anymore. I think about so many things and sometimes I don’t even understand myself. And just thinking now, maybe it will be easier to write like blogging was a best friend I have and I tell them everything. I think I’m going to write that way, it will be easier to talk then to think about writing. It funny how I got 5.5 in the F ACT writing but I always think I can’t write. I think I underestimate myself sometimes. May it’s my learning disability? But do I have one or I’m underestimating myself again? Well I’m not going to put a lot of thought into this and move on to bigger and better things.
