Is studying abroad worth it?

Hi! I'm 23 years old and Im considering studying in South America I have family there and I can get 210 credits in psychology in only 3 years and a half "3 trimesters per year", which is equivalent to a Masters degree in the US, I already know exactly what needs to be done because my mom did the same thing for the same major and it all worked out. The "entire" career costs less than only 1 semester in the US, its such a great opportunity (no loans to pay off and no distractions) and as far as Ive heard it looks great on a resumee. BUT I love my life in the US Im so happy here, it would be a huge sacrifice.. Im gona be almost 28 by the time Im done and theres nowhere Id rather be than here at home :[! Success is truly my #1 priority but Im confused & I wanted to know if you guys think it would all be worth it in the end considering personal experiences? Am I gona regret it if I dont do it? Thank you so much for your answers and sorry its so long!
