TAOM- your seriously so mature! You should know your very lucky that at such a young age your having conflict with your parents. I am only having it now (marrigable age) and it very hard for me because Im not used to it and I dont know how to handle it. Funny enough this is life and its NORMAL!!! So shkoyach to you, really!
Anyways, as for finding a mentor, this is how I found mind, but everyone is different. Im a natural shmoozer so I make bonds quite easily, but I found that the people who seem more geuninly intrested tend to follow up with me, meaning I am not always the initiator, they will initiate conversation.
Now, noone needs to “adopt” you, but everyone needs a mentor, so finding one could just be sitting in class one day and realizing this teacher is really inspirational, you can start with small talk and see where it goes and if she seems like a down to earth, understanding person open up to her! Im sure they will be more than happy to help you!
have an increadibly spiritual and beautiful Shabbos 🙂
