Life decisions, adult adivce, college, work? HELP😕🥺🤯

I’m 17 and I am a very indecisive person. Making huge decisions does not come easy for me, and it doesn’t help that I literally have NO ONE around me to help and offer actual meaningful advice, so it would mean the world for me if any of you have any life advice in general. Basically I live with my dad and step mom, who might I add is like an evil stepmom from hell, she has done me wrong multiple times and controls my dad in every aspect. Her kid who is 20 and in college is the angel child, she got the 2017 Malibu and is not expected to pay any penny of it and has not had a job for 3 years now and is handed money. I am told I don’t work enough, I’m in college failing 2 classes and got dropped from my other class and my mental health is falling off a cliff. I KNOW failing the classes is my fault, but honestly I told my dad I was not ready for college (I graduated early) but I was still forced to go. I wanted to start college at my four year university that I was accepted to, but like I said I was forced to go to the technical college where I’m obviously failing. This semester has made me resent both my parents, college, and myself and I don’t know what else to do. I know no one can organize my life for me, but what do I do?!? I don’t have money to move out and my dad and step mom act like they will throw me out on the streets if I don’t go to college. I don’t know what I would do without college, but i also don’t know what I’m going to do with college and I feel like I would eventually go back when I’m ready. My issue is so I want to be happy now and work on myself and mental health now, or do I want to be unhappy going to college for what may or may not be my dream career and be happy 4 years down the road. I just feel like I am compared to my step sister and don’t amount to what she is, and now that I no longer have the motivation to go to college I can’t please my parents and they might not even let me live here. Everyone makes it seem like if I don’t go to college I will amount to nothing, but it’s honestly killing me going to college struggling with classes and trying to be happy.
