The majority of the mistakes were because you didn't used the past tense.

La mayoria de los errores fueron por no usar las los verbos en pasado.

Today is Thursday and I am very tired on my bed after a nice day. It is near to midnight right now. In the morning, I went to the village market with my mom and we bought natural foods for a lot of money. At lunch, we ate fish with potatoes. We had lunch with my father in our little house. In the evening, I went to the tennis public court in my city to play with my friends. I'm disappointed because I lost the final game, but happy for the opportunity to enjoy this magical sport. Now I'm resting with a lot of pain in my foot after a hard day in my life.

Today is Thursday

Today is Thursday and I'm very tired (it is close to midnight). I am lying on my bed after a nice day. In the morning, I went to the village market with my mom. We bought fresh food (or do you mean organic food?) and spent a lot of money. At lunch, we ate fish with potatoes with my father at the little house. (The meaning of "at the little house" is not clear). In the evening, I went to the city's public tennis court to play tennis with my friends. I'm disappointed because I lost the final game, but happy for the opportunity to enjoy this magical sport.

Now, I'm having foot pain and resting after a hard day.

 

Please  pay attention to tenses! I or I'm should always be capitalized. 

Today is Thursday

Today is Thursday and right now I am very tired lying on my bed (it is close to midnight) after a nice day. In the morning I went to the village market with my mom and we bought natural food for a lot of money. For lunch we ate fish with potatoes at my father's little house. In the evening I went to the public tennis court in my city to play tennis  with my friends. I'm disappointed because I lost the final game but happy for the opportunity to enjoy this amazing sport.
Now I am resting with some foot pain because of this busy day in my life.
