Crying easily and at loud voices. How can this be treated?

Hello doctor,

I cry a lot even on little things on little words, loud voice tears come into my eyes too much. I face worst days of my life. I was happy suddenly everyone at home turns their behavior bad. I am little one of my siblings and my age is 22 years. From my childhood, everyone says I will cry and I start crying. Then I grew up. Now one at home scold me but then I fell in love, they disrespected me and they stopped my education and whom I love was not able to marry as his education is not complete he did not have any job. He was also very aggressive I needed love, care, attention but he fought with me to leave my friends five years. All this continues then now I gave up on him because I cannot bear my family worst behavior with me. He has his job now, he is little changed. He is loving me, we were planning how to make agree both of families for our wedding but yesterday he again talked about that days I broke up with him. But since childhood and these put bad memories in my mind so even on little things tears come into my eyes and everyone got fed up because of the tears. I want treatment of this, please.
