As an English teacher, I will tell you that the first thing you need to do is sharpen your grammar skills. You say that you are an honors student, so you need to write like one. You know that the first word of a sentence is capitalized and that the personal pronoun I is always capitalized. You have left apostrophes out of contractions (can't), misspelled several words (habbits, comptetitive), used the wrong (weather instead of whether). If you want to raise your grade in writing, you're going to have to proofread to correct errors like these.
You say you have been impaired, but you don't say how. I can onlly guess that it must be some sort of physical condition. In that case, I would say that it is commendable that your GPA is 3.45, which is a perfectly acceptable score. I would counsel you to work on your writing and grammar skills and consider yourself successful already. You're putting too much pressure on yourself and probably working too hard. Relax and take a break. That may be just what you need!
