Struggling with weak iman and distracted salah... any advice?

Assalamu alaikum everyone. I've been praying regularly alhamdulillah, but lately things have been tough. Exam stress and some depressive feelings have really pulled me away, and honestly, I'm embarrassed it got to this point. There are certain mistakes I keep slipping into, and it's scary thinking if I passed away now, where I'd end up. Any tips on how to get back on track?
