Y i am depressed

I feel like a loser even though i am going to university so I am technically doing something w my life, but i am unsure about it and dont really have much passion for it and dont expect to get a good job that i will like after im done. I am barely getting by in school atp. Also im 2 years in and im realizing that the stuff that im learning seems pretty unimpressive and not useful. It does not feel rewarding or like it will lead to anything, and my current life situation has me depressed i just want to get away from my hometown and my family its all i care about. Running away and going homeless and living in my car even seems so appealing to me, and two of my older siblings did exactly that and i understand why they did it but im too scared i guess well maybe its more that i dont have the motivation to do everything i would need to do to properly prepare. I feel stuck and not in control of my life and i want to be free. I obviously want to be successful but i cannot see myself being successful at all i have no idea what i am doing. It sucks because its like no matter what route i take its going to be bad it feels like there is no way out. I just want to be happy and i want to want to live so badly. And ive been so isolated for so many years and ive been trying to reach out but i cant find friends in this city. I feel like im wasting my life and i am not as far as i wanted to be in life by now. I wish i was so much better and i dont even know where to start also i am a 20 yr old man and i just hate not being fully financially independent. I worked so much from 15-20 and i regret it so much it made me realise how much i hate the concept of trading ur time for money i cant see myself being happy w a normal job again that pays a fixed salary. How are you supposed to feel motivated to improve or keep going? I hate money i only want to make a lot of it so that somebody will love me for it.
