Moved with family to the states but its not good

Hey guys i feel worried about the uncertanty of my futere. Quick brief about me,im was born in miami, mother then moved to Puerto Rico 19 days after my birth.I ve been raised there all my life, a lot of dangeorous shit been going down there high % of poverty because of corruption due to politicians, this made people steal,sell drugs and murder a lot of people. You get it its a real shit hole, i always wanted to get out of there due to this, i was planning on leaving when i was done with the university( this is my last semester towards graduation),to live in the states it didnt matter what state i could live as long as i got out of here.Ok bare with me almost done kinda, well i got into a fight with my uncle who live with me,grandma, mom and my lil bro. He is a mentally unstable person,veteran suffers from ptsd. After that my family (dad,mom,bro, and me) fearing for my safety decided to make a fresh now start in florida, been here almost a month we live in a family friend's house because we are low on money.i Was positive to make a fresh new start, mom was being and still is a downer, dad is a dreamer to the extreme always taking about the oportunity that life has to offer but he has been unsuccesful do to him taking bad decision then he starts talking shit, he has had multiples chanches on getting a job here due to friends helping out, then when he gets a job he complains and quit, then repeats the process again,i now i can get a part time not a fulltime(cuz im studying) and help my fam but hes been telling not to get one because we could move to another city in florida any moment and low and behold were moving in a few hours to a apartment to live with my dad's friend, its a small apartment and the guy has served time abd sell dope on the side while working. MOM is saying if things dont go well in here she moves to Puerto Rico, she said i can go with her or take my chances here with my dad and be a failure like him. Point is if im here i want to make the most of it do what ever i can to be sucessful here not in Puerto Rico i see no future there i rather die than go there. Point is what should i do ride this out and be optomistic or wait till shit hits the fan and go to Puerto Rico. Crist im 21 and feel like a child, helpless not being able to do anything even though i want to prove myself. What should i do????
