Too stressed out in matriks life

Have you ever feel so stressed out you feel like you want to leave everything behind and just go far far away to a calm and peaceful place. I have so many assignments left unfinished, so many chapters I haven't gone through. I've slept in most of the lectures. I have problems picking up from what the lecturers teach in our tutor. PSPM exam is another a month to go. Pleaseeee someone please help me. I don't want to fail again although i did tried my very best.
