Regretting my postgrad...

In September 2023 I joined a postgrad (not comfortable saying what exactly, but it's within the EECS department) on a part-time basis. I got through this year but failed a module (got a first on the coursework but failed the exam worth 80% of the module miserably). I did well last semester, and got a first in my modules. This semester not so much, I got a pass one one module and failed the other. But due to my good results in semester 1, I should still average a first this year if I pass the resit for the failed module according to my calculations.
My issue isn't really with my grades or abilities. I know I'm capable, I just didn't enjoy semester 2 modules at all. My social life is also bad. I'm not expecting to have the same experience as undergrads would, but I've managed to make no friends at all. I did make 1-2 course mates, but they're full-time students so finish this year. I've also lost contact with 1 of them and I'm not close with the other.
Uni is a chore to get to. Also the teaching sucks. No offense, but certain lecturers can't even speak English properly or just read off slides.
I'm just wondering - should I stick it out? I have another year to go and graduate in 2025. I suspect I'll be even more stressed next year having to do my dissertation and all, but I've made it this far.
