Can anyone give me advice on which prayer to say?

I’m having a really hard time at the moment with stress and work and uni and many other things.

I’m getting a bit overwhelmed with the way my course at university is being taught with all the restrictions and lockdown in place, the workload is insane and it’s being taught 3 times as fast. I also teach at the university too which adds to the stress. I’m not sleeping for days at a time and I feel like I’m going crazy.

What prayers are there that I could say in this situation? I feel like praying (along with other things like playing video games and binge watching TV shows) is keeping my sanity

Thanks
