Переведите на , с учётом грамматики, а не через переводчик "жаль, что ты оказался в такой ситуации. не грусти, вот тебе мои советы. перестань обращать внимание на "старших детей" которые говорят гадости про тебя. ничего не скрывай от своих родителей, они тебя любят и поддержат, ты обязан им все рассказывать. нужно побороться с стеснительностью, ты и сам не заметишь как изменился в лучшую сторону. надеюсь мои советы тебе ."

That's a pity, what you at such situation. Don't be sad, I will give you my advices now.
Stop taking attention to "older children" who says yuck about you. Don't hide something from your parents, they love you and they will support you, you must tell them everything. You have to overcome with shyness, you won't observe how you will change to better way.
I hope my advises will help you.

Every man has his own preferences – «tasted differ». Each of us is carried away by occupations that we choose according to our wishes. Some people like going for sports, but some doesn’t. Someone would love to embroider, someone considers embroidery tedious and boring.

For example, I love collecting various trinkets and souvenirs. This activity is very fascinating for me and I am delighted with it. I love to write poetry, draw and read. Most of all I love to read detective stories.

My cousin hates sitting at home. She likes active lifestyle much more. Recently she has taken up playing tennis. In general, in her spare moments she is not averse to sing some foreign song in French. She adores the French language, traditions and customs of the Frenchmen. In the future, she plans to pay a visit to France and call on her aunt, who has been living there for already 10 years .

My elder brother is crazy about cars. He collects old cars, restoring them to his style. In addition, he is a very athletic guy. He goes to the gym three times a week and does exercises for 2-3 hours there. As for me, I hate sports. For my part mental exercises are more important than physical ones. But my brother thinks otherwise. He holds the opinion: «A sound mind in a sound body».

Summer is my favorite time of year. I leave to the grandmother in village and I will help her. Planting potatoes, watering flowers and more. My grandmother, I'm only a month and a half. Then my father and mother go to the seaside. I first see the sea. Daddy will you teach me to swim. And I'm like a fish to swim.
This summer will be just wonderful! 
перевод:
Лето мое любимое время года. Я уеду к бабушке в деревню и буду ей. Сажать картошку, поливать цветы и другое. У бабушки я буду всего лишь полтора месяца. Потом мы с папой и мамой поедем на море. Я  впервые увижу море. Папа научит меня плавать. И я буду как рыба плавать.                    
Это лето будет просто чудесным!
Надеюсь подойдёт))
