I live in an area that also has decent bus coverage with stops all over, although I've never actually taken the bus. I can't take the bus to work because there aren't stops where I need to go. I also attend school 19 miles away, and depending on traffic it's anywhere from a 30-45 minute drive. Last year my car broke down and I looked into taking the bus to school for the few weeks I would be carless. It would have been a 5 1/2 hour trip each way, I would have had to take 3 or 4 buses, transfer between 2 different companies, and I would have had to walk several miles in between stops to get from the first bus company's stop to the second's. Realistically, I couldn't have even left on time to make it to class or gotten back home while the buses were still running, even if I wanted to waste my life riding buses. I worked an extra 100 hours of OT that month to pay for my rental car.
Cal2 is hard! Especially if you have a learning disability. I have ADHD and I strongly suspect dyscalculia, and am just really really bad at math and I went into Cal2 straight from Cal1 (while attending college in my 30s) and I still thought I was going to lose my mind. There were many tears shed in the first few weeks but I kept plugging away at it, used all the resources I had available, the Internet, school tutors, stayed after class to talk to my instructor and went to his office during office hours. Eventually about halfway through the semester the switch clicked in my brain. I got my first ever 100% on a math test in my life, and I got an A overall in the entire class. My instructor told me at the end that he was proud of me and I walked out of class and cried happy tears instead of the furious frustrated tears I had cried at the beginning.
Good luck, remember to be patient with yourself and show yourself the same love and grace you would show another person who is struggling with a learning disability and the adjustment of returning into an academic setting. Don't be afraid to look stupid, don't be afraid to ask for help, and use any resource you can. When I started my Cal2 class I sat down with a tutor who happened to be one of the college math instructors and I said "I think I've forgotten everything I know about math, can you help me refresh on what I need to know for Cal2 because I'm panicking." She actually had a cheatsheet saved with all the concepts that students needed to know to start into Cal2 and I used it not only to study but to refer back to and still have it and occasionally refer to it.
You can do this!
