Ouch!!! my knees are killing me!!!

Eiks... my knees! Its really hurt:(
Actually, I started to feel the pain a week ago, its all started when Rifqa slept outside in the living room on the couch while waiting for me to finish my homework (English Literature, owh!). So, after I had finished my homework and cleaned up my mess (books apparently~), I tried to wake her up. However, she was really tired, and she hardly opened her eyes. I told her, "Rifqa, common and sleep in the bedroom," She just ignored me. I knew she was in a very deep sleep. So, I said to myself, " I can't let her sleep outside alone, if not she will be crying in the middle of night when she find out that she was sleeping alone in the living room, ". So, with the strength that I had that time, I had to carry her to the bedroom. Uh, she really heavy though! She weight almost 28Kg~ At first, I hardly felt anything after I carried her to bed. However, the next morning, after I woke up from sleep, I felt that both of my knees were really hurt as if they were knocked by a hammer! Knock...Knock...Knock

As the result from the pain, it effects my day in school. First and for most, in my P.E (Physical Education). Every Tuesday, we have our P.E with the Year 11 at the Sporting Club (FYI, I'm in Year 10). We have to run around a football pitch every time during P.E to warm up. Because of my pain on my knees, it made me fell more difficult to run. Besides, I even add the pain to my knees as we had to run around the pitch twice and had a football competition among us. That day, after came back from school, I straight away took my bath as usual and after I performed my pray and ate my lunch, I went straight to bed at about 6 o'clock ( thank goodness, I didn't have any homework that day). Quite early though~Hu Hu...I was really exhausted! It fells like it was a really long day for me! Not to mention my pain on my knees. The very next morning, I told my mom about my pain. She then asked my dad to buy me a pair of knee guard. I still have to wear them until now as I can still feel the pain. But, I'm actually feeling better right now. Alhamdulillah...
