Healthy body is fortune

Today my sister and cute nephew came to my side. I am very happy I had long time didn’t see the little guy since we met last time. I had not seen the little guy for a long time.
I miss him so much.
We decided to go shopping after they arrived.  Because most markets are discounting on having sales, as far as we know, girls are like to go shopping so we think that the good chance should be grasped.(better - that this opportunity should not be missed) 

After we visited some shops, suddenly I felt uncomfortable, with a headache and stomach pains.  which is too feeble to I didn't faint at that time, then and we went to hospital. Fortunately it wasn't serious not seriously, after eating some tablets it is better now. Thanks God for blessing me.

It's easy to get illness sick recently, I wonder if it's caused by my growing age getting older.
At present, with the growth of age as we get older,  being healthy is becoming more and more important for people’s our lives.  life   Everyone wants to have a healthy body especially for those people who have experienced the plague form illness; compared with others they would not care for about being  rich or poor. Gradually, they view earning money not  as an important  part of the life.  not all, Spontaneously their attitude for life will soon change d.

Anyhow, from now on, I wish hope I can always stay far away always from these strange diseases.   The people who surround ing me are happy ily and healthy every day, I will cherish every minute s of my life working hard, studing hard... 

good!

many of the mistakes are more idiomatic than grammatical
- to get sick is general, to get an illness is more specific
growth of age would be correct but we use the phrase getting older
hope is a little stronger than wish - I hope I get good grades (probably I can).  I wish I could get good grades (probably I can't) 

keep writing!
