I’m 25 years old (26 soon) and i’m still unclear about what I want to do career wise (in the long term), currently I work in higher education but I don’t see myself there for long. What advice would you give for trying to figuring out the right career path?

Don't put pressure on yourself first and foremost. There are so many successful people who didn't actually figure out their ideal career path until their 30s/40s. I'd say, take some time out to consider your strengths and what you enjoy. There are lots of tests online that could also help you determine which kind of jobs suit your character. It may mean doing something to get by while you figure things, but whatever happens, don't feel disheartened.

I’m currently in my final year of university and I’m struggling a lot to keep up with anything. I feel extremely demotivated in everything and having fears of failing. Do you have any advice to get back on track ?

Think about how far you've come. The fact you made it through to your final year is a testament to your perseverance. Be proud of yourself for getting this far and understand that if you've made it this far, you're more than capable of seeing it through to the end.
Also, don't fear failing because the truth is that getting great grades in University is not the be all and end all. I know people who didn't do as well as they wanted or who didn't go to University at all and they lead happy and very successful lives. Also, some organisations don't even care what mark you achieved, as long as you have a degree. Just try your best without applying so much pressure to yourself. I think once you get rid of the pressure, you'll feel more motivated to finish. 
Also, one more thing that may help you feel motivated is adapting to a routine. Wake up at a set time, eat at a set time and study at a set time. Eventually you'll get so used to the routine that studying will just feel like a natural part of your day. 
I hope that helps!
