<human>: Condense the text into a few key points

So not sure how to start but my issues are more about personal issues I'm dealing with my girlfriend and her family. How does that relate to my question? Well, I got accepted to a state university in California for mechanical engineering. Although I should be rejoicing this admission after not doing so well a few years back at another previous university, I am rather contemplating whether if I should transfer out due to circumstances. I'm currently living in my girlfriend's parents and her parents are not exactly the best support group I have right now but are at least helping me be at a better state economically. My parents can't support me financially because of their health issues so it was best that I seek to live on my own. Due to this, the girlfriend decided to let me live with her family. Now, to why they are not the best support group? Well, to start out they want me to be on the look out for my gf. Taking her to work and picking her up regardless if I have homework the next day or need to catch on sleep; the issue is I don't have a car so usually either walk to her job, bus it, or get an Uber  to get home after picking her up. I work a part-time that is normally between 25-35 hours per week (depends how busy we get) while going to school full-time right now in computer science at my local community college. Her stepdad is strict so if I do see my parents(which live about 30 miles from where I am now and takes 2 hours on public transportation one way), I am not allowed to sleepover. My brothers ask where am I and I just say I'm so and so place. My dad covers for me whenever they are more demanding to know where I'm at. Lastly, since the gf is on paying back her student loans, I'm not sure if me quitting my part time job will upset my gf and piss her stepdad because I doubt he'll be supportive of me going to school full-time and not working. I just want to succeed in school but I'm afraid to fail miserably again after my plan to go to pharmacy school went to disaster the first time I was at a university. Sorry for the long read.
<bot>: I want to go full-time for mechanical engineering but highly doubt the gf's step dad will not approve of me not working.
