"I opened my eyes to find a streak of light seeping through the closed window blinds."
"Window" is unnecessary, because that's where blinds go. Other than that- thumbs up.
"My mind fought it's way through a fog of last night's events in all effort to forget about it."
This sentence is grammatically incorrect. "It's" should be "its." "In all effort" is not grammatically correct, and doesn't make sense. I see that you're trying to produce strong imagery, but you should choose more precise words.
"A sudden fluid of pain rewrapped itself around my heart and there entered the guilty conscience my heart desired to avoid."
"Fluid of pain" doesn't make sense. Is "rewrapped" really what you mean here? "There entered" should be changed to be something more clear. You might want to rethink using the word "heart" twice in the same sentence.
You're obviously a beginning writer, which is really good, but you should practice- and by practice, I mean read. A lot. Don't worry about "copying" the style of your favorite authors, it will actually help you develop your own voice.
For help, try reading Stephen King's "On Writing." It really clears up a lot of issues beginning writers have.
Please don't take my criticism personally. I'm trying to help you out- if you love to write, keep writing! Getting feedback (especially the negative kind) is supposed to help you grow as a writer, not discourage you from continuing.
