Sounds like you've been thoroughly demotivated by a couple of teachers. Are they good teachers? Are they themselves passionate? I would say be careful who you take advice from. And I realise that's slightly ironic coming from someone you've never met.(Original post by fefssdf)
See this is the problem I wouldn't say I have much of a passion for anything to the point where I'd wanna study it for 3 years . I'm passionate about education and learning in general but I don't wanna be s teacher anymore I don't think so I'm rather lost
A maths degree will give you the option to teach, and teaching is a great and rewarding way to have an impact on people. Good teachers are priceless. So I would say: don't do anything stupid, and stick with plan A for the time being, but always be on the look out for a plan B. Many plan Bs are compatible with a good maths degree.
Finally, it sounds like you've got a slight lack of confidence. But you don't have to be a maths proof genius to get a 2:1, you just have to work hard and ask questions, so don't worry about that.
Go to university, enjoy it, and take some time thinking about your career. Plenty of people don't even have a plan A in their final year, so you're ahead of the curve in that respect.
And nail your exams this summer
