I’ve been told I have a bad reputation and attitude, and I desire to change.17M

Today, I’ve been told I have a bad reputation, attitude amongst my previous instructors and classmates by my current instructor. My reputation has diminished a lot with my classmates this school year due to me isolating myself( basically being only out for myself ) and having run-ins with my instructor displaying my bad attitude because I have a hard problem saying ok. This has caused me to have a bad reputation that I desire to rebuild it and reform into a good one. To help my reputation my instructor told me I should interact with my classmates more but I feel like I’m forcing myself if I do if that makes sense and this is how I felt before now. I don’t really desire to get to know or have conversation with them because I just came to solely learn not get to know people but in the setting we are in that’s a flaw to have because I’m showing I don’t have a sense of comradery? I really would just like advice and honest truth. No sugarcoating because I want to grow from a boy to a man. Thanks to whoever sees this post. I hope you have a good day and won’t mind spilling some gems.
