Think about yourself and what makes you happy. Always be with someone who loves you the way you do and respects your emotions
Don't use phone , don't see movies, songs regarding love , spend time in playing any games with friends , go for some trip even nearby place , be with friends , remember everything happens for reason , you will get what you wish
Just cut off and stop thinking about that person.
Start give priority and love yourself first rather then anyone because no one is yours except your parents so spend time them.
