Idk anymore

My life has been completely falling down. My boyfriend of three months left me for one of my best friends. One of my friends was shot and killed last year when he was with his family. My aunt and stepdad, two of the most important people to me, screwed up and left the family, and to top it all off, today I got a call from my mom and was told that the police called and my cousin was found dead and they don’t know if it was a suicide or murder. She was living in Texas with her abusive boyfriend and her two little girls who are 2 and a new born. Her boyfriend had just gotten out of jail. Idk what to think anymore. Please help me. I don’t mean to sound whiny I just need help because I don’t know what to do.
