A Diary Entry I wrote on 28 July 2013 (one of my diary i wrote in 28.07.2013)

My dear diary,today is Sunday and I have stayed at (i stay in) home (as same), as usual. Actually, I (i) have been keeping myself busy with my studies (study) almost every (each) week which (and this) has (which) almost worn (weared) me out (every time). Even though I (i also) look forward to the weekend, I have no idea why I (i) continue (keep) pushing myself to study on Sundays. (something ,)  Perhaps I have the feeling (it makes me feeling) that i can be a useful member of society (person for society and the world).
I studied from 7:00am to 6:00pm(taking about 1 hour for (having) a meal during this period). After I (i) had supper, I (i) went to take a bath, which gave me a fresh surge of energy (made me feel energetic suddenly).Then, I (i) made a mask to care for my skin while I (i) listened (was listening) to some light music. To tell you the truth I (it) was more tired than usual (days,) but I (i) had (have) no choice but to keep moving. All my friends try (tried) to talk me around, saying (that) it is not (no) necessary (necessity) to take everything seriously, you (yuo) do really need to have some fun. I always know that, but I (i) also know it is not the right time to enjoy myself and that I (i)  must make every second count (counts). When I (i) become strong enough and am (be) able to help and protect my family, all of my friends, and the people around me who care for me,then I (i) think (that) is the time to (i) enjoy my life. Of course, I (i) admonished myself on occasions  (complained some times,) but moaning (complaining)  is always a luxury for me, I (i) can gain nothing (good) from it.  Fortunately, I (i) have always overcome this setback (got over from it) quickly always, so it has no impact (impacted nothing) on me.
Well, today's almost done (it's almost up today,) so see you tomorrow, my dear diary.

Hi, Vicky - main point is to remember to use a capital 'I' on every occasion. I have made a few amendments to help it read better.
