Love the new job but dislike new life

I moved away from home for an amazing job. I love the job and living with roommates instead of my family (parents/siblings) is nice but very different. But I miss my family, and I got a flat tire which I noticed the morning of my 1st day of work so now 2 days later I still have a flat (despite people offering to help get it fixed only thing been done is it got air in it then the next morning was flat again ) So I’m going on to day 3 of my car has a flat and can’t move, I only have the food I packed so I really need to go grocery shopping (only so long can I live on oatmeal, snack food, and food my roommates share with me). But I live in a house on the property of my job and the nearest town is a short drive away but too far away to walk. As well the tap water is currently not for drinking unless boiled first and expected to be like that till around the end of this month.
