Issues with my period. To my period?

One week before my period , I was okay and very good . Two days before my period , I started to get angry and lose it and crying , then when period begin I started crying none stop at everything , even things that makes me happy . I am very emotional , and I feel empty and depressed , and can barely focus on anything . School life has become torture and going to school everyday is imposible to imagine . I have hard time focusing on anything including school and any conversation . This all happened as soon as my period started . I noticed my acne increased& my breast got bigger . But sometimes I get very happy and normal , even life I used to be before ( those 5 days for now ) but I go back to feeling blue and depressed and very emotional during the day . Is this linked to my period ? How can I get treated if that's possible
