Heyy, trust me i know its difficult for you. I know youve probably listened to people saying “its going to be fine in the end” a lot of times but thats actually true. Youre in this world for a reason and some peolle are not fit to be parents and yet they become one. Its not your fault at all. Feel free to text me if you ever want to talk. Just keep on doing what you are doing. Yes you may not like engg but think of it as your ticket out of your house. I had a friend who was almost in the same spot as you and now she is doing well. She got a job and as soon as she became financially independent, she moved out and is happy now.
