Here are the corrections:
-
I have a best friend who I could talk about a secret and share some concerns.
→ I have a best friend with whom I can share secrets and concerns.
Error: "A best friend" → "Best friend" doesn't need "a", and "could talk about a secret" is unnatural. "With whom I can share secrets" sounds more natural. -
We've known from high school.
→ We have known each other since high school.
Error: "We've known" should be "We have known each other". "From high school" should be "since high school", as "since" is used for time references. -
At back then I went ahead every way.
→ Back then, I took the lead in many ways.
Error: "At back then" → "Back then" (Remove "at", as "back then" is already an adverbial phrase). "I went ahead every way" is unclear and should be "I took the lead in many ways." -
We everyday got along, I used to look after her about violin skills and informations about that.
→ We got along every day. I used to help her with her violin skills and provide her with information about it.
Error: "We everyday got along" should be "We got along every day". "Look after her about violin skills" is incorrect; "help her with her violin skills" is more natural. "Informations" is incorrect because "information" is uncountable. -
I went to higher universty than her.
→ I went to a higher-ranking university than she did.
Error: "Higher universty" → "higher-ranking university". "Than her" should be "than she did" to complete the comparison. -
I got a many chances than her.
→ I got more opportunities than she did.
Error: "A many chances" is incorrect; use "more opportunities". "Than her" should be "than she did". -
When we went to same an ochchestra I felt happy.
→ When we joined the same orchestra, I felt happy.
Error: "Went to same an ochchestra" should be "joined the same orchestra". "Same an" is incorrect; use "the same". Spelling error in "ochchestra" → "orchestra". -
But I am surprised that I see to her.
→ But I was surprised when I saw her.
Error: "I am surprised that I see to her" → "I was surprised when I saw her". The sentence is in past tense, so "am" should be "was", and "see to her" is unnatural. -
After get in social field, she was better than me I tought she had more practice and efforts.
→ After entering the professional field, she became better than me. I thought she had practiced more and put in more effort.
Error: "After get in social field" should be "After entering the professional field". "She was better than me" should be "she became better than me". "I tought" is a spelling mistake; correct it to "I thought". "More practice and efforts" → "practiced more and put in more effort".
Final Edited Text:
I have a best friend with whom I can share secrets and concerns. We have known each other since high school. Back then, I took the lead in many ways. We got along every day, and I used to help her with her violin skills and provide her with information about it.
I went to a higher-ranking university than she did and had more opportunities than she did. When we joined the same orchestra, I felt happy. But I was surprised when I saw her after entering the professional field. She became better than me. I thought she had practiced more and put in more effort.
