I’m 20 and I feel extremely lost

I am a 20 years old male thats lives in California and have been lost for a while in where I want my life to go, I am debating if i should go to back to college and get a engineering degree or go straight to the blue collar work. I really want to go back to college however my family and I are lower income and I am basically the only person who can get my family out of poverty. I feel like if I go back to college i would let down my family because they depend on me. I am currently going to trade school for line work however I don’t like it but if i go the blue collar route I know i would get money faster and help my family out but I feel like my heart is in college I’m just lost right now but want to help my family out financially
