Can I still graduate with a 2:1?

I have gone through a really tough time at university facing a lot of mental health issues. But I’ve still made it to final year. I got a 3rd in first year which counts as 10%. A 2:2 in 2nd year which counts as 30%. Final year counts as 60%. I am aiming to graduate with a 2:1 as it’s a waste of time if I get anything lower but I just submitted my research proposal for my dissertation that I was aiming to get a first on as I need to get a first class in final year in order to get a 2:1. I received my mark despite massive effort and got 65% for this research proposal. The research proposal counts to 10% of the final mark for the dissertation module but I’m worried that I won’t be able to get a 2:1 anymore as I was aiming for a 1st class in all of my assignments in order to get a 2:1. Can anyone advise me on what I can do please and if it’s still possible to get a 2:1?
