ite or repeat?

18 yr old this yr just finished o lvls and did badly had chosen the route to repeat but currently struggling with attendance and mental health issues that it’s affecting my studies because I have a phobia of doing my homework what if it’s shit again and I can’t do it and also missing lessons. Received a msg from teacher to rethink my choice because I have been escaping school. Other option is ite and I am able to get into some good courses but no science courses and it’s 3/2 yrs duration . But I am scared that I would not be able to get good grades there for project works and be 21 years old in polytechnic . Have some old ex friends there that I lost connection to because I went to express and left them behind. I keep feeling stressed about whether my choice is right. Repeat or ite?
